Does the Pfizer vaccine require two shots?

Yes. It’s 3 weeks apart. Moderna is 2 shots, 4 weeks apart. Johnson & Johnson is 1 shot. 

I hear they have to be 3 weeks apart. But I read today (4 15 21) that a third dose will be needed 6 months to a year later, with annual booster shots. Google it.

Here in America, after you get the first, you get the second one 21-28 days later.

Yes and they are doing ours 4 months apart.

As far as I am aware all the COVID-19 vaccines require two doses: an initial dose and a booster. The research published by Pfizer-BioNTech produced the advice that the two doses be given three weeks apart.

I live in the UK and our government has been giving the doses about 12 weeks apart. Its intention was to get as many first doses delivered to as many people as possible. Research has shown this is OK. I do not think the government would have done this if it meant the vaccine would be ineffective. It would simply mean the vaccine programme would not work.

My first dose was Pfizer, by chance (I had no choice), and my second one was Pfizer, which I chose. I decided it would be better to have the same vaccine. Research has only just got under way to see if having your two doses from different vaccines will be effective.

I am happy to say our vaccine programme here in the UK is going very well. One of the few things the government have got right during COVID-19. That's because the NHS are delivering it. Anything that has been done during this pandemic by the NHS has worked well. Things done by the private companies, owned by the cronies of government ministers, have been an appalling disaster and a criminal waste of taxpayers' money.

Yes, Pfizer and Moderna are both 2-shot vaccines, the shots can be up to 4 months apart.

Don't get the vaccine, my dad died 8 days after getting the second dose and he was shredded and super healthy. RIP Bigs, I love you!!!

yes, the pfizer-biontech vaccine is given in two doses, and so is the moderna-vaccine. Getting only one shot would be less effective.

Governments are considering giving them 12 weeks apart to give more people a first jab sooner
