COVID-19 Vaccine Dosage Definitions

“Full vaccination” was defined as follows: two doses, in any combination, of BNT162b2 (Pfizer-BioNTech) (7 (link)), mRNA-1273 (Moderna) (8 (link)), ChAdOx1 nCoV-19 vaccine (AstraZeneca) (9 (link)), Gam-COVID-Vac (Sputnik V) (10 (link)), CoronaVac (Sinovac) (11 (link)), or NVX-CoV2373 (Novavax) (12 (link)) or at least one dose of the Ad26.COV2.S vaccine (Johnson & Johnson, Janssen) (13 (link)); and ≥14 days between the last vaccination and the PCR test. “At least one vaccination” was defined as one or two doses of any of the vaccines listed above and ≥14 days between the last vaccination and the PCR test. The participants who checked “others” were not included in either “Full vaccination” or “At least one vaccination”.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
