+1?

Also looking for info about the Moderna same question.
(asking as someone who had pretty rough s/e to first shot a year after recovering from covid.
I got the moderna and had covid about 6 months earlier. After the first, I had the chills and slight fever after first dose. Nothing after the second,  but I was taking ibuprofen around the clock after I received the second dose.

This summary shows more reactions to Moderna vs Pfizer to first dose:  fever: 8.2% vs 5.8%, chills 8.4% vs. 5.5%.  So yeah, more side effects, but not a huge difference.  https://www.sltrib.com/news/2021/03/26/comparing-covid-vaccines/

There was also a specific rash that was reported for Moderna, about a week after injection.  https://www.massgeneral.org/news/press-release/MGH-researchers-call-for-greater-awareness-of-delayed-skin-reactions-after-moderna-covid19-vaccine

Also slightly more allergic responses with Moderna: 
Scientists from Massachusetts General Hospital and Brigham and Women's Hospital administered email, text, phone, and smartphone app survey links to 64,900 employees who received a dose of one of the two mRNA coronavirus vaccines from Dec 16, 2020, to Feb 12, 2021.

A total of 25,929 employees (40%) received the Pfizer vaccine, while 38,971 (60%) received the Moderna vaccine. Eighty-one percent returned at least one symptom survey, which were sent each day for 3 days after vaccination.

Among all vaccinated employees, 1,365 (2.10%) reported acute allergic reactions, defined on the survey as itching, rash, hives, swelling, and/or respiratory symptoms. More Moderna vaccinees (2.20%) reported symptoms than Pfizer vaccinees (1.95%).
https://www.cidrap.umn.edu/news-perspective/2021/03/very-few-severe-allergic-reactions-tied-mrna-covid-vaccines

So, yes, slightly more side effects with Moderna, but not 3 times as much, so not obvious that it would relate to the weight of the vaccine.  What contributes to that difference in weight?  Is it a difference in the amount of mRNA, or are there differences in the amount of lipid and sugar included in each vaccine?   I really don't know the answers to any of these. 

But speaking of drawing conclusions from an n of 2:  My mother had no reaction at all, while I had a sore arm both times (Pfizer).  I had read that side effects decrease with age, so from this I concluded that my mother must be older than me.   ::)

I wonder if the sore arm is a result of the vaccine in the blood system or the needle / vaccine in the arm, in which case it may make a difference how the actual injection is administered

Anyone have a good answer to why antibodies are not good enough for all these things you need to be vaccinated for, or have a recent covid test (such as sports games in NY)?
Yes, the vaccines are more effective at preventing illness than a prior infection, especially with variants

Politics.
I wonder what people who type "u" instead of "you" do with all their free time.

I'm looking to get the J&J vaccine. Does anyone know where I can get in Brooklyn?. Everything I find in vaccinefinder says no appointments available.

Maybe we can start a new thread for this?

Poll:
https://www.dansdeals.com/more/free-stuff/get-free-laminated-copy-covid-vaccine-card-will-get-covid-19-vaccine/

What does the poll have to do with the laminated card?

Also, surprised how many respondents didnít have COVID, though Iíd think theyíre more likely to vote on such a poll.

Had COVID with antibodies, and looking to get vaxxed soon. Haven't been following closely, what's the better course of action to prevent COVID long term, and which has least side effects?

1 shot of Pfizer/Moderna
1 shot J&J

I don't plan on taking 2 shots bec. FWIU it's unnecessary for COVID recoverers.

I donít think this question has been studied or a conclusive answer is known, but you can ask your doctor.

The data we have (for those who havenít been infected) seems to show marginally better efficacy with Pfizer/Moderna single dose vs JNJ, but there isnít any long term data yet.

As for side effects, I donít think there are comparative studies and all vaccines have a significant likelihood of some immediate side-effects that pass and donít leave any long-term effects, and an extremely small risk of more serious side effects that are so rare theyíre considered negligible.

Thanks, regarding side effects - not concerned much about long term side effects, rather which one is more likely to knock me out for a few days.
