The vaccine is only 52% effective starting two weeks after the first dose. When you get the second dose, the vaccine is 91% effective seven days later. This is a reckless headline. https://twitter.com/thehill/status/1344292928215281665
Here’s the data straight from the New England Journal of Medicine highlighting the efficacy of the Pfizer vaccine. You’re not going to be automatically immune to Covid after the first dose. It takes time.
Deray retweeted my first tweet, so it’s only a matter of time before some foolishness enters my mentions.
I’m going to do a thread on the journal article about the Pfizer vaccine if I have time later today because a lot of people who got their science test grades placed face down on their desks are getting too loud.
Ok, I’ve finally got some time. Here’s a thread on the Pfizer vaccine from the New England Journal of Medicine.
The research study for the Pfizer vaccine had 43,448 volunteers. 21,720 received the vaccine and 21,728 received a placebo. For the purpose the study, only 37,706 people were included in the safety subset.
Side Effects:
For the Pfizer vaccine study, most of the side effects were localized. The most common side effect was mild-to-moderate pain at the injection site within 7 days after an injection with less than 1% of participants across all age groups reporting severe pain.
For the Pfizer vaccine study, most of the side effects were localized. The most common side effect was mild-to-moderate pain at the injection site within 7 days after an injection with less than 1% of participants across all age groups reporting severe pain.
“Pain was reported less frequently among participants older than 55 years of age (71% reported pain after the first dose; 66% after the second dose) than among younger participants (83% after the first dose; 78% after the second dose).” Most resolved in 1-2 days.
For the systemic side effects, the most common side effects were fatigue and headache. This is from your body opening the message it receives from the mRNA in the vaccine and responding to the spike protein like this.
Fever was reported in 0.2% of participants after the first dose, but 16% of people under 55 and 11% over the age of 55 had a fever after the second dose. This is where the vaccine goes to work. Your body sees the same message from the mRNA and responds like this.
Adverse Events:
Lymphadenopathy - swelling or inflammation of the lymph nodes.
This occurred in 64 vaccine participants and 6 placebo participants.

This occurred in 64 vaccine participants and 6 placebo participants.
Adverse Events:
There were four serious events in the vaccine group. These events occurred in just one participant each:
Shoulder injury related to vaccine administration
Right axillary lymphadenopathy
Paroxysmal ventricular arrhythmia
Right leg paresthesia (numbness).
There were four serious events in the vaccine group. These events occurred in just one participant each:
Shoulder injury related to vaccine administration
Right axillary lymphadenopathy
Paroxysmal ventricular arrhythmia
Right leg paresthesia (numbness).
These adverse events were seen in 4 out of 19,000 participants.
Two vaccine participants died. Four placebo participants died. However, they were all unrelated to the vaccine study. Also, nobody died of Covid in either study group.
In the three weeks between the first and second dose, 39 cases in the vaccine group and 82 cases in the placebo group were observed, resulting in a vaccine efficacy of 52% and showing the vaccine can begin providing protection as soon as 12 days later.
Of the 10 cases of severe Covid-19 that were observed after the first dose, only 1 occurred in the vaccine group.
The study was intended to be a 2-year study with the placebo and vaccine groups. But, it would be reckless to not tell the participants which groups they were in during a whole pandemic. So, the placebo group won’t be tracked long term because they obviously need a vaccine.
The study does not look at the efficacy in children, pregnant women, and immunocompromised people.
The study also doesn’t specify how and when people caught Covid. They don’t specify if they wore masks or practice social distancing. So people who caught Covid after getting vaccinated may have been out here raw dogging the air and we’ll never know.
Long story short. The side effects are all anticipated results that your immune system would have. The vaccine isn’t 100% effective. We don’t know if you can still pass Covid along after getting vaccinated. We also don’t know if the vaccine works long term of if you need boosters
As someone who works in a hospital, I was chomping at the bit to get my shot this week. You have the right to be skeptical and ask all necessary questions to make your own informed decision. But, with how selfish America is, I wanted my vaccine ASAP.
End thread. And if you feel the need to call me out of my name, please remember to put “Doctor” in front of it.
