Just had my J&J shot 1hr ago.
The ONLY reason I got this shot now was because it was announced and confirmed by the pharmacist that after next week J&J will not be an option in Massachusetts.
The reason given was due to weak dispensed numbers, for whatever reason people want the MRNA vaccines.
I wanted to stick with the traditional viral vector type of vaccine vs the new MRNA. Was really hoping for more time to evaluate. Wish me luck.
J&J is about 4% of vaccine injections in the US. Why?
Being 3 months later than Pfizer and Moderna may be a factor. The
LIEden Administration bungling of the blood clots (at a rate about the same of in the general population) possible side effect probably hurt J&J.
Viral vector vaccines are actually fairly new. Last I heard something like 5-10 viral vector vaccines are in use. The traditional vaccine technology uses dead, weakened, or inactivated viruses. The only three Covid vaccines of that type in use that I'm aware of are SinoVac's, Sinopharm's, and a vaccine developed in India. The two Chinese vaccines apparently are not very effective against variants currently in circulation. Maybe SinoVac's and Sinopharm's vaccines are two variant specific, or maybe they just aren't very effective in general. I've not heard a lot about the Indian vaccine (except that it's not the main vaccine being used in India, unless only recently).
