Within the early days of the pandemic, a strutting, hip-shaking dance pattern took over social media: the J. Lo TikTok Challenge, a roughly...


One dose of the Pfizer/BioNTech COVID-19 vaccine is 85 p.c efficient in stopping symptomatic illness 15 to twenty-eight days after being administered, in line with a new study reported in The Lancet. Presently, the Facilities for Illness Management and Prevention (CDC) recommends that the U.S. persist with the two-dose routine with vaccinations occurring 21 days aside, the method that was examined in medical trials and permitted by the Meals and Drug Administration (FDA). That dosing routine offers 95 p.c safety towards the virus. The CDC just lately suggested that ready as much as 42 days between the primary and second doses could be OK.

The brand new examine bolsters an analysis by different researchers printed in The New England Journal of Drugs (NEJM) that estimated that one shot of the Pfizer/BioNTech vaccine is 92.6 p.c efficient after two weeks. The identical researchers additionally discovered that one dose of Moderna’s COVID-19 vaccine is 92.1 p.c efficient after two weeks.

In response to the NEJM evaluation, Pfizer researchers noted that various dosing regimens haven’t been evaluated. They added, “The choice to implement various dosing regimens resides with well being authorities; nonetheless, we at Pfizer consider that it’s crucial for well being authorities to conduct surveillance on carried out various dosing schedules to make sure that vaccines present the utmost attainable safety.”

After all, the query is whether or not we should always “present most attainable safety” for people or for populations. Again in December, I requested, “Why use two doses of COVID-19 vaccines when one works almost as well?” I identified the truth that we may double the variety of Individuals vaccinated towards COVID-19.

Equally, in a current Washington Put up op-ed, George Mason College economist Alex Tabarrok requested:

Is it higher to provide a second dose to at least one individual, boosting them from 80 p.c to 95 p.c protected, or to provide a primary dose to another person, elevating them from 0 p.c to 80 p.c protected? Ethics and effectivity each recommend that it is higher to guard two folks effectively than one individual maximally. It is also a faster path to herd immunity, a key a part of any vaccine technique.

In different excellent news, Pfizer is reporting that its vaccine now not wants ultra-cold refrigeration and might as a substitute be saved for 2 weeks at temperatures generally present in pharmaceutical freezers and fridges. This significantly simplifies and speeds the vaccine’s wider distribution.

New stories concerning the efficacy of a one-dose routine are vindicating the UK’s resolution to delay the second dose of those vaccines by 12 weeks in order that provides might be stretched with a purpose to inoculate extra folks extra rapidly. Let’s hope these new information prod the Biden administration into making an analogous resolution quickly.
