Modrena hopes to offer Covide-19 boosters that combine its first vaccine in the fall with anti-oxidant protection. On Tuesday, initial reports indicated that such an approach could work.
Today’s CV-19 vaccines are all based on the original version of Corona virus. But the virus continues to change with the immediate threat of the highly contagious omega-3 variant – and its siblings.

Prior to Omiron’s arrival, Moderia was studying a combination of protection against pre-existing differences. On Tuesday, the company announced that the beta-original vaccine combination had produced more antibodies that could fight off a number of variants, including oxycodone, than today’s standard stimulant.
Although the increase in antibodies is modest, Moderna’s goal is to produce a composite bullet that specifically targets the omega. “These results really give us hope,” said Dr. Jacques Miller, vice president of Mordana, who said the next step would be better.
Tuesday’s information was reported online and not verified by independent experts.
The CVD-19 vaccine still provides strong protection against serious illness, hospitalization and death, and even oxycodone. That difference is so different from the original coronavirus that it easily overpowers the immune system, although studies in the US and elsewhere show that the original booster dose strengthens protection. Some countries offer secondary incentives, especially to vulnerable individuals. In the US, people 50 years of age or older have a severely weakened immune system.
Health officials have made it clear that giving incentives every few months is not the answer to the mutation virus. They began consulting on how and when to change the immunization schedule.
It is only dangerous to switch to the latest variant of the vaccine, as the virus may change again. So both Moderna and rival Pfizer are experimenting with what scientists call a “bivalent” shot – a mix of each company’s first vaccine and an Omicron target.
Why does Moderna’s previous, beta-focused combination shot have any effect on omicron? It includes four mutations that mimic both the beta variant and the new Omicron, Miller said.
Moderi and O’Micron are now experimenting with a better-looking bivalent shot – including 32 mutations of that difference. Two intensity scale studies are underway in the US and UK; Results expected by the end of June.
