By ‘catching’ I mean being bed ridden by it. You still get it….just the effects are MUCH lower.
Yes, severe illness is reduced. As virtually all patients with severe COVID have one form of sepsis or another. Which is caused by your immune system over reacting to a new virus.
However, if you already got COVID, your likelihood of severe illness is about the same as getting vaccinated. T-cell memory prevents your immune system from over reacting even if your overall antibody levels are low.
Based on apparent reduction in spread in highly vaccinated countries, it is likely that vaccine is reducing the risk of "catching" covid as opposed to allowing you to catch it (and spread it) but you are asymptomatic.
Not really. Many countries, including Israel where the first such report came out, do not test asymptomatic or mildly symptomatic people who have been vaccinated. So while Pfizer acted monetarily that their vaccine is responsible, the Minister of Health in Israel clarified what was in, but ignored by the media, in the report.
So when 60%+ of your population is exempt to testing unless they land in a hospital bed. You don't really know how well it's transmitting.
What we do know, even here in Canada, fully vaccinated staff and patients at hospitals are getting COVID, still getting sick and even dying post being fully vaccinated. Most recently Toronto Western Hospital's outbreak including fully vaccinated nursing staff.
This vaccine isn't the silver bullet that the polio or MMR vaccines are. This is more of a therapeutic that primes your immune system preventing sepsis. Which is what we need, but playing it up by calling it a vaccine does a disservice to all the other vaccines and just gives anti-vaxxers more fuel.
