If it worked they wouldn't worry about the unvaccinated.

[thelonerider]

Efficacy and facts are irrelevant when the gov't says "do it or I take away your job and ability to buy food".

[Random-rtec]

As a rule, good products sell on their own & don’t require mandates.

[apatterson]

Just 6 months until your next booster! For life

[Bookhermit]

It's called "moving the goalposts". When it doesn't have the predicted effect, you instead find something else about it to take credit for.

[ctrlaltdel]

If it is so safe and effective, then allow the pharmaceutical labs to be sued. Why are they not liable for their products?

[jfawkes]

If they worked well we'd already be getting back to normal...

[TheMattj]

If it worked, mandates wouldn’t be a part of the discussion.

[leroylem]

It's all about eugenics, money and power...

[murphy]

Natural immunity doesn't make as much money.I got covid and it wasnt that bad but you wont see the news talking about the millions of cases like mine. 2 days, no fever, no cough, not even a headache.

[spanchagn]

I got break through case, just after 3 months after my second dose 🤯. It was a mild infection though. I think cdc is not counting all the break through cases.

Key takeaways:
1. The Pfizer study tested 44k people for "symptomatic" covid infections. (What symptoms were they looking for? Why didn't they test for asymptomatic infections?)
2. People were either give the Pfizer jab or a placebo. (What percentage of people received the placebo? Was it an even 50/50 split?)
3. Out of 44k people in the study, only 170 displayed "one symptom" (So again, assuming that there were at least 22K people in the placebo group who did NOT receive the vaccine, a MAJORITY of unvaccinated participants did NOT contract symptomatic covid)
Pfizer will never admit that infected people have a 99% survival rate WITHOUT taking the jab.

When dodge cites the "initial quality" of a vehicle, does that mean it's going to outlast a Toyota?

When a Covid vaccine is touted as being initially 95% effective, I think of those commercials.

[Surfmus]

I just heard one of my coworker, a covid19 vaccinated lady in her 70s passed away from COVID-19.

[HShango]

I'm just so glad I've not caught covid (period)

[nyquil]

These comments questioning so called "authority" give me hope in humanity.

[hillbillybeerdranker]

When they were first released, they said 97% would be immune and not catch Covid. They also said you would have immunity for life.

[matdolor]

Someone should keep track of how many times the goal posts have been moved. It’s happened so many times yet we still keep playing the game

[lisalee]

We should wait until the studies reveal even more on long term effects....poor kids...so sad

[lifeispoetry]

Idc
Kinda tired of hearing about it
