Allergic Reactions to mRNA Covid Vaccines?

Morbidity and Mortality Weekly Review (MMWR), a publication, of the CDC, reported on 21 cases of anaphylaxis between Dec 14-23rd following vaccination with the Pfizer vaccine.  Anaphylaxis can occur after any vaccination and these are cases from the first use of the Pfizer vaccine after their FDA Emergency Use Authorization was granted.  There were 1.9 million Americans who received the Pfizer vaccine during that period, for an incidence of 11.1 cases of anaphylaxis per million vaccinated.  These reports were sent to the CDC through multiple safety reporting methods, and after an initial review there were 175 cases that needed to be carefully assessed and only 21 cases of anaphylaxis were found. The diagnosis of anaphylaxis was based on a worldwide scientific system of classification of anaphylaxis.  17 of the patients had a history of allergies and 7 of the patients had a history of a prior anaphylactic episode. 

The median age of the patients was 40.  Ninety % were women.  The median interval to developing symptoms was 13 minutes with 14% occurring after 30 minutes.  All patients were treated with epinephrine and recovered.  One patient was lost to followup.  81% of these patients had a history of allergies: drugs, medical products, foods, insect stings.  These cases were spread geographically and none received vaccines from the same lot numbers.   

After review there were 83 cases of non-anaphylactic allergic reactions: itching, rash, itchy and scratchy symptoms in the throat, and mild respiratory symptoms.  67% of these patients had a past history of allergic symptoms. The remainder of the cases reviewed were non-allergic, i.e. like vasovagal syncope (fainting).

I watched the CDC broadcast on vaccine allergic reactions several weeks ago, mainly because  I have multiple allergies.  These are their recommendations:

1.  Any patient who has anaphylaxis to either the Moderna or Pfizer vaccine, should NOT be vaccinated again with those vaccines.

2.  Any patient who has a history of anaphylaxis to a prior vaccine (i.e. influenza etc) or to an IV drug should consult an allergist and their risk vs benefit ratio to vaccination assessed.

3.  Any patient with allergies to foods, animal danders, insect stings, meds (given orally), eggs, gelatin, and/or positive family history may receive the vaccines. 

Vaccination sites should screen patients for allergies, have medical resuscitation equipment and epinephrine in prefilled syringes available, and observe all patients with allergies for 30 minutes post vaccination, instead of 15 min.  Data from the Moderna vaccine experience will be reported soon.  Only one case of anaphylaxis was reported early as far as is mentioned in the press.

The Path Forward Combating Covid-19 - Dr. Francis Collins

I listened to an excellent interview of Francis Collins, Director of NIH and Dr. Fauci's boss, this week.  He talked about multiple aspects of the pandemic and I wanted to share some of that information. 

He did not accept the idea of giving only 1 dose, or two half doses of the current Pfizer and Moderna vaccines to spread out the vaccine.  The very high efficacy of these vaccines was obtained in clinical trials of 15,000 (Moderna) and 22,000 (Pfizer) volunteers using 2 full doses.  "Science must prevail" - there is no guarantee that the efficacy will remain high, especially in the different subgroups, if the dosing regimen is changed.  He also was hopeful that the current vaccines will be effective with the new mutations (UK and S.Africa), and this is being studied in the lab.  RNA viruses mutate all the time, and the US was not studying the genomic changes of isolated viruses like the UK.  The CDC has now set up a comprehensive genomic testing lab to follow the mutations.

The vaccinations started slowly, but this is partially understandable.  There is a learning curve for this as with anything else.  He wants to make sure that more than 1 million people are vaccinated per day with a goal of vaccinating 80-85% of the population to achieve herd immunity.  State Governors meet virtually, weekly, to share their experiences and advice with vaccine distribution.  He believes that vaccine availability might be the limiting step, but hopes to have the population vaccinated by summer.  See below

There is still vaccine hesitancy in different groups.  The government developed many different ways to assure the public about the safety of the vaccines.  He stressed that dying of Covid-19 is a MUCH higher risk than having a side effect from the vaccine.   There are many different approaches being used to meet with groups of people through churches, community centers, and groups of community leaders to expand the number of people who will be vaccinated.  For those who wonder about historical distrust of the government re: "experiments," look up the Tuskegee Study in Wikipedia. 

Dr. Collins said that he speaks to Dr. Fauci every night and they both disseminate information using scientific facts.  One fact I want to emphasize:  After you are vaccinated you must still follow the Public Health guidelines until we achieve herd immunity.  We know that the vaccines were highly effective in the clinical trials, but you don't know if your personal immune response is as effective when the community virus rates are so high.  The virus will still be spreading until herd immunity is reached.

My Covid Year: March-December

                                                    GnomeCopySIZE200.jpg

My blog will be 14 years old on Jan. 4th. I was partially retired and enjoying daily drawing in a sketchbook when I discovered Danny Gregory’s Everyday Matters Yahoo Group. It was the perfect inspiration for me, both for drawing and playing with watercolor paint. After following the Yahoo Group for several months, I decided to start a blog so I could share occasional sketchbook pages with the group. Each year, almost from the beginning, I wrote a blog post about my Progress throughout the year, and my specific Goals for the coming year - per recommendations from the EDM Group. That is impossible to do this year.

My Overall Goals always were: To develop better drawing and painting skills on paper, and dye-painting skills and surface design on fabric.

My specific goals for 2020 were:

Take classes to keep inspired and motivated.

Maintain a community of artist friends.

Deliberate Practice - planned activities to practice specific skills: drawing figures in motion.

Bookbinding: making all of my watercolor sketchbooks

Progress: During January and February I sketched with the Urban Sketchers and went to Art Exhibits at a Gallery, Met, and Morgan with friends to sketch. Then on March 1st a traveler returned to NYC with Covid-19, and the following day a lawyer from Westchester County, who worked in Manhattan, was diagnosed. There was no travel history, thus suggesting the community spread of the virus. My husband and I decided to stay at home and each of us only left the apt to take a neighborhood walk daily.  On March 20th our governor issued a "Stay at Home Order," and in NYC it lasted until June 8th. I amused myself with lots of reading and continued to practice drawing figures in motion (from photos). As a retired physician my reading included lots of coronavirus information - usually press releases because it was too soon to reach the journals.   

I was still drawing figures after breakfast for my sketchbook and in May I began to sketch figures to illustrate a little bit of Covid-19 science and posted them on my blog. In July I’d learned enough about our pandemic to give a virtual lecture on Covid-19 to women in the STEM program at my undergraduate womens college, including mRNA vaccine development. It was this project that gave shape and meaning to my days at home. I posted collages and Covid information on my blog and in the NYC Urban Sketchers and Everyday Matters Facebook pages.                                                                

My major Goal was to remain home, stay healthy, and figure out how to amuse myself. Anything else that I did evolved over the full 10 months since March 1st.

1. Read exactly 80 books, mostly fiction, and many old classics.

2. Posted 67 collages with figures with a little SARS-CoV-2 science for each.

3. Walked in my neighborhood at sunrise since June 8th, drawing anything of interest - the first ones were painted, the rest are pen and ink only like my Gnome.

4. Made watercolor sketchbooks and almost filled 4 that each have 48 pages.  The collages are also in the sketchbooks.

5. Zoomed with grandchildren, art friends, and lifelong friends from other cities - some with standing weekly virtual "visits."

6. Followed FDA and CDC meetings online to gather information about Covid-19, vaccines, and threatments.

7. Watched streaming cultural events and series with my husband in the evenings.

8. Started a weekly virtual ballet barre class with my regular teacher from STEPS.

9. Learned how to make tight fitting 2-3 layer cotton masks for family.

10. Made 12 Coronavirus Christmas ornaments for our family - transferring a watercolor painting to fabric which I then used for a 3 layer ornament.

My Goals for 2021: Get my vaccine with Group 1b and remain healthy. I’m convinced that the rest of the time will be filled with things that will evolve naturally and that I can’t even imagine now.

SARS-CoV-2 Mutations: Experts Weigh In

SARS-CoV-2 is an RNA virus and these viruses can mutate every time they divide.  If you isolated the virus copies from an individual infected cell, the group of virus copies might all be slightly different based on the mutations that have occurred.  The RNA pictured in my cell drawing has 30,000 building blocks and any one can change, which affects the amino acid it makes for proteins.  Some mutations increase transmission and/or severity, others do nothing, and still other mutations decrease transmission and/or severity.  

These viruses have spike proteins over their surface, and there is a binding region on the spike that attaches to a receptor on our cells and allows the virus to enter the cell and multiply.  Mutations in the spike protein part of the virus are more likely to have an effect on the disease, but it takes many animal and laboratory studies on the virus to determine the effect of dominant variants before any conclusions about the infections can be verified.  Read Below

Dr. Racaniello, Professor and Virologist at Columbia  University, is concerned that the UK variant is being hyped by the  media  and the epidemiologic data from population studies can't be used to accurately predict biologic changes in the infection.  He says "I do agree we should look into these things but until we have some data we should be careful about what we say."  In studies done on the coronaviruses that cause the common cold it took up to 5 years before they were significantly changed by mutations. 

Several days ago Dr. Fauci said they are trying to get samples of the mutant variant from the UK so they can study it at NIH.  And now a young man in Colorado (with no travel history) has been found.  At this time there is no data that should make us worry about the two vaccines.  They postulate that the mutations affect transmission, but there is no data that suggests that the infection is more severe.  Dr. Osterholm, epidemiologist at the Univ of MN, said on his weekly podcast that if there ever is a mutation that blocks the vaccine,  the mRNA vaccine can be altered in as little as several months.  The collective advice from these scientists is to stay calm, wait for conclusive lab studies to be done, and get vaccinated whenever you can.

HAPPY HOLIDAYS 2020

We had a very quiet Christmas.  Since the pandemic first began we limited our time out of the apartment and have only seen our NYC children and grandchildren for limited times - on the sidewalk in front of our apartment, on socially distanced blankets on the grass in Central Park twice, or when they drive past to leave or pickup items.  ZOOM to the rescue!

We do have a Christmas Tree and enjoyed two full days reading and listening to classical Christmas music in the living room. next to the tree.  It was a change from our pandemic reading/TV room so it was special.  I'm posting a photo of the tree, with ornaments I made over almost 4 decades.  And I included a close-up photo of the ornament I made for this year.  I made 12 - and everyone in the family has one or will have one.

This ornament was made from my watercolor painting.  I cropped and sized it so I could fit 4 images onto a plastic backed 8.5 x 11" sheet of fabric which I then printed in our ink jet printer. I used 3 sheets for the 12 images and then used regular sewn techniques to make each one.  Our oldest son ran across town yesterday to pick up 8 for his and his sister's family when the rain stopped.

Wishing everyone a Happy New Year and a healthy 2021.
