Astra Zeneca has a good vaccine that is very similar to the Sputnik or J&J for that matter and would be expected to have a similar efficacy and safety profile. They have done a horrible job of managing their trials, though. The US has millions of doses of A-Z stockpiled and is using them for "vaccine diplomacy" at this point sending some to Canada and Mexico where it is approved. The Biden admin has so many doses of others ordered that we may never need it. On the other hand, J&J continues to have production problems, so who knows?
Millions and millions of doses have been given around the world so there should be plenty of real world data on it by now though that lacks the rigor of a clincal trial.
I don't think anyone believes the number of confirmed cases is actually how many have had it. My entire family had it, yet I only got tested. They literally told us not to bother getting the other 4 of us tested. All of us had the classic covid symptoms.
And yet I had all the symptoms last year and this year, tested negative and tested negative for antibodies.
So no, I don't believe the inflated numbers. A lot of us just had colds or flu.
AstraZeneca vaccine appears safe—but experts say efficacy results were based on 'potentially misleading' data
AstraZeneca, accused of inflating the efficacy of the vaccine, promises to release updated results soon. If they validate the vaccine's safety, it could help ease concerns after reports of blood clots.
About 20% of the population have had it at this point. However immunity tends to decrease over time. Many have gotten it twice. Even the vaccine does not prevent it you from getting it or spreading it. It will just be mild.
Decreasing immunity isn't proven because it hasn't been around long enough to be proven.
Researchers examined data from employee health records of more than 36,600 health care workers in California and found that ​less than 1% tested positive for COVID-19 after being fully vaccinated -- meaning both doses plus two weeks for the immunity to build -- with the Pfizer or Moderna vaccines.
While anecdotal reports of individual doctors getting COVID-19 after receiving one or both doses of the vaccine have been covered in the news recently, the study offers a more comprehensive look at how often such post-vaccination infections occur in fully vaccinated people. "This study confirms that the vaccines are highly effective at preventing COVID-19," study authors Dr. Shira Abeles and Dr. Francesca Torriani told ABC News.
Granted, this would be far more useful if we knew what percentage tested positive in this sample group before the vaccine was available, but they do have very strong evidence from how much the numbers plummet during the vaccine timeline:
Quote:
The research also showed that the further along in the vaccination process health care workers were, the better the vaccine worked. Of the 36,659 workers vaccinated, 379 tested positive after their first vaccine dose, with the majority of those individuals testing positive within two weeks of their first shot. After receiving both doses of the two-shot vaccine, 37 people tested positive, with the majority testing positive less than a week after their second dose. Only seven health workers tested positive 15 days or more after their second vaccination.
Not a single vaccinated health care worker who contracted COVID-19 was hospitalized or died and those who did get sick appeared to have milder symptoms than the unvaccinated, according to the researchers.
The anti-vaxxers claiming these vaccines don't work look more ridiculous with every passing month...
Astra Zeneca has been paused in Canada and Germany for those under 55 and 60 due to blood clot concerns.
Norway for a while paused the Pfizer vaccine early in the year, Moderna vaccine too Iirc for similar reasons. A large group of elderly vaccine recipients died in a care home after getting the Pfizer vaccine, and also cases of ex. health care workers and doctors dying of blood clots after getting the vaccine, like the doctor in Florida with no prior history of ever having blood clot problems. This is why the risk benefit numbers are so important, it's going to vary a lot from group to group and it doesn't make sense for low risk people to get a COVID shot. Though there are even some questions for high risk people, if it tends to cause clotting problems or other severe side effects for elderly patients, that it raises questions about how useful the vaccines are in general. We need a lot more specific data to break down the risks and benefits for each group, and a lot less media flogging in general. Just show us the full data without trying to put a slant on it.
