Some doctors are also suggesting that people will need booster shots every year....🤡

That is identical to flu vaccines .

So it IS like flu vaccine..

And it’s not even effective for one whole year? And they say U can still catch it as it doesn’t prevent it, only reduces the severity once U get it...

Pfizer and Moderna reduce infection risk bb 90-95%. Far greater than the flu vaccine which is around 45-50%. And even if the small chance you catch Covid, it's very mild and reduces mortality to less than 1%.

what about AstraZeneca

Around 60 to 70% effective.

Although mRNA vaccines are highly effective, they are the *first* vaccines to use this technology. So uncharted territory.

By comparison, the Russian Sputnik (aptly named, as it was the first one launched), has efficacy of 90 - 95%, and uses proven technology, and can ALSO be stored in a refrigerator in solid form.

Btw, in India, currently the best available is ingenuously developed Covaxin, which is highly effective as well!

So in your opinion Sputnik is better than moderna and Pfizer?
obviously the best vaccine is the one being offered to you right away but if someone is getting it privately, do you think Sputnik is better than those two?

Does this mean if someone who is vaccinated, gets exposed to coronavirus there is a 90-95% chance they won’t get infection?

Yeah that's the idea, their risk of contracting Covid is reduced significantly. My husband is currently working inpatient at a county hospital. A lot of his colleagues caught Covid last year. Since vaccines, he hasn't heard of any of the residents or attendings catching Covid.

In the outpatient setting, none of my colleagues caught Covid, nor the medical assistants. Before vaccines I would get so many video visits with Covid symptoms and subsequently so many positive Covid tests. Now, I don't recall the last time I tested someone for Covid. From the urgent care side, one of my patient tested positive for Covid. That's a huge change.

Not just infection but severity of symptoms if you do get it.

One common misunderstanding is that 95% efficacy means that in the Pfizer clinical trial, 5% of vaccinated people got COVID. But that's not true; the actual percentage of vaccinated people in the Pfizer (and Moderna) trials who got COVID-19 was about a hundred times less than that: 0.04%

What the 95% actually means is that vaccinated people had a 95% lower risk of getting COVID-19 compared with the control group participants, who weren't vaccinated. In other words, vaccinated people in the Pfizer clinical trial were 20 times less likely than the control group to get COVID-19.

That makes the vaccine "one of the most effective vaccines that we have," Barker told Live Science. For comparison, the two-dose measles, mumps and rubella (MMR) vaccine is 97% effective against measles and 88% effective against mumps, according to the Centers for Disease Control and Prevention (CDC). The seasonal flu vaccine is between 40% and 60% effective (it varies from year to year, depending on that year's vaccine and flu strains), but it still prevented an estimated 7.5 million cases of the flu in the U.S. during the 2019-2020 flu season, according to the CDC.

And none of the three vaccine trials looked at all for asymptomatic COVID-19. "All these efficacy numbers are protection from having symptoms, not protection from being infected," Barker said. (Some early studies hint that the Pfizer and Moderna vaccines also reduce the number of viral particles in a person's body, called viral load, and the likelihood of testing positive at all, which would cut transmission. Still, because we don't yet know that for sure, people "can't throw away their mask" once they're vaccinated, Barker said.)

But all three trials also used a second, potentially more important, definition of "cases." What we care most about is protecting people from the worst outcomes of COVID-19: hospitalization and death. So Moderna, Pfizer and Johnson & Johnson also measured how their vaccines performed against severe disease (which meant severely affected heart or respiratory rate, the need for supplemental oxygen, ICU admission, respiratory failure or death).

All three vaccines were 100% effective at preventing severe disease six weeks after the first dose (for Moderna) or seven weeks after the first dose (for Pfizer and Johnson & Johnson, the latter of which requires only one dose). Zero vaccinated people in any of the trials were hospitalized or died of COVID-19 after the vaccines had fully taken effect.

Yes, in my humble opinion (I'm not a medical professional, so please take with a grain of salt).

I would advise to take whichever you have available as soon as you legally can. 👍🏼
