"Get whatever vaccine you& #39;re offered first" is good public health advice, but I still wanted to get "the best" one.

So I did not consider getting the Johnson & Johnson vaccine at first because of the "low" efficacy rates, but after doing some reading I changed my mind. (Thread)

First I thought that a 66% efficacy rate meant that 1/3 of people in the non-placebo group in the trial ended up getting COVID. But that& #39;s not how it works.

This rate is lower than that of the other vaccines but is still excellent.

Second, you can& #39;t really compare the trials done for the J&J, Pfizer, and Moderna vaccines. The latter two were done earlier in the pandemic.

The J&J trial was done later on, in several countries, and they have data on its effectiveness against some COVID variants

So I& #39;m not an expert in this stuff but to me it makes total sense that the J&J efficacy rate would be lower than the others when it was tested against different variants, while the other vaccines were not.

I know this isn& #39;t quite the same, but like, if someone said that toddler 1 is 94% likely to eat a vegetable, and toddler 2 is only 50% likely, but toddler 1 has only ever had potatoes, while toddler 2 has tried a wider variety of veggies...you get the idea

So, after I realized that the J&J vaccine& #39;s efficacy rate isn& #39;t bad at all, and that it was tested against COVID variants while the other vaccines were not, I was still wondering if 2 shots were better than 1 and if that had anything to do with how effective the vaccines are

And I learned that getting a 2 dose vaccine isn& #39;t necessarily better than getting a 1 dose vaccine. You only get one dose with the J&J vaccine because that& #39;s all you need for your body to develop a good immune response.

And besides that, getting 1 dose is more convenient. It gets people fully vaccinated faster - in 2 weeks instead of 6. That& #39;s good for public health, and it& #39;s good for individuals who want to go back to partying or licking doorknobs or whatever y& #39;all did before the pandemic.

The one dose vaccine is also good for people who will have trouble making two separate appointments for a variety of reasons. There will be people who can& #39;t afford Uber, or can& #39;t get a ride, who will have to sit on a bus for several hours to get to a vaccination site.

So after hours of research & learning that I had nothing to worry about, I got the Johnson & Johnson vaccine this morning.

They& #39;re doing 3000 shots every day at the FEMA vaccination site in Orlando (Valencia West Campus on S. Kirkman). 7am - 7pm. Bring your ID #OneAndDone

Ok, back to my Twitter hiatus. Get vaccinated so you can lick doorknobs again.
