My citation is old but my doubts were true as evident from real world data from most vaccinated nation Israel. You cannot deny the facts as such as the Pfizer trail data doesn't have those details.

I was highly suspicious from that time that more than 90% efficacy is highly impossible and I was proved right now with actual efficacy.

So your fact is actually obsolete. The real world efficacy in mid of July from Israel has come so low to 39%.

Your reply seems to suffer from appeal to authority bias as it doesn't have any appreciable facts which can stretch ones grey matter.

If you are a knowledgeable person and an expert, please give your views for the below questions:

1. Why SARS-COVID-2 is asymptomatic for some, just mild symptoms for many and only for a very few it becomes serious. Then why vaccination should be given to all rather than finding the root cause of why it becomes severe in some? Majority of the people who have died due COVID-19 are those who are very old and those with comorbidities . Why not administer vaccines only to those who are vulnerable to this virus?

2. As per data available, young people less than 40 years rarely get serious due to Covid. Natural infection works equally better for them and they develop antibodies to it, then why not spare a thought for natural infection for younger population?

3. Antibodies produced by vaccines are only for 3-6 months ,and now already there is talk to take booster dose every 6-12 months. Doesn’t this reprogram the way our immune system works? To be always dependable on vaccines?

4. Vaccines for polio or small pox or measles work because they are non mutating or less mutating virus. Vaccines for HIV OR FLU doesn’t work as they are highly mutating virus. Corona virus is a highly mutating virus and vaccines don’t stop infection and this explains the low efficacy as time progresses. Since virus keeps on mutating this efficacy will further decrease.

5. Just like efficacy dropping, the case for hospitalization and death will also increase as days progress due to breakthrough infection as evidenced in UK and Israel recently which is seeing increased hospitalization and death. Moreover even CDC acknowledged that the viral load is same in vaccinated and unvaccinated population.

6. It is well known that antibodies to vaccines are very specific. For example antibodies produced against corona virus spike won’t protect against other virus like flu or chicken pox. How the body is going to be affected by these viruses in long term?

7. Why is it not advisable to take antibodies test after vaccination to ensure that there is protection against future infections?

A. As per experts 2-3 weeks after first dose of vaccines antibodies are produced by body specific to spike of corona virus .

B. If no antibodies are detected after two doses of vaccines is the person still protected?

C. Also even if antibodies are produced if they don’t last after 1 or 2 months is still the person protected?

D. Moreover even if antibodies last for several months, if virus mutates, can the specific antibodies produced in the past protect against the new variant?

8. How to trust the PCR test which cannot differentiate between live and dead viral fragments. Why there is no mention of cycle threshold at which the detection happened. Since the virus is spread so much it may be present in every person in low load or dead fragments. How to prove that all those infected and dead had low Ct values to show that they had high viral load and had the live virus? Are you sure they aren't false positives?
