The Johnson vaccine gives eight months immunity at least, according to a press release we link to below. It’s a lengthy document so we touched sides with Ralph Ellis at WebMD to learn the basics. However, we should mention this is very much preliminary information. That’s because the data comes from two small-sample, preprint studies awaiting peer review.
The Role of Preprint Studies in COVID-19 Research
Breaking news, even of great importance can take months to appear in medical journals. However, researchers are naturally keen to make their findings known, and frustrated by the very necessary verification process. So what they increasingly do instead is publish research informally, in order to update their colleagues soon as they can.
The evidence that Johnson vaccine gives eight months immunity therefore lies in draft research papers. However, this does not, in itself diminish the importance, and the scientific accuracy of the findings. WebMD summarizes these as follows:
1… The Johnson vaccine ‘elicits neutralizing antibody activity against the Delta variant at an even higher level than against the Beta variant’.
2… Johnson vaccine ‘generates a strong neutralizing antibody response that does not wane; rather, we observe an improvement over time.’
This information goes a way towards allaying concerns over recipients requiring a second shot. We look forward to publishing confirmation, soonest we hear the results of peer reviews.
About the Johnson Vaccine Providing Eight Months Immunity
The Johnson product is a single-shot, COVD-19 vaccine, compatible with standard medical storage and transportation protocols. The press release confirms ‘the vaccine remains stable for an estimated two years at -4°F (-20°C). And a maximum of 4.5 months at routine refrigeration temperatures of 36° to 46°F (2° to 8°C).’
Johnson and Johnson is an American multinational corporation dating from 1886, that develops medical devices, pharmaceuticals, and consumer packaged goods. It has well-established delivery chains which may better position to supply clinics in remote, rural areas.
