By February, states may have hit their stride on vaccinating residents. Vaccination campaigns may move beyond hospitals and nursing homes, rehabilitation centers and other such facilities to pharmacies and medical practices.

More vaccines may be authorized or at least ready for authorization by January or February. It’s clear that Moderna and Pfizer alone cannot cover the US population. AstraZeneca, Johnson & Johnson and Novavax all have vaccines in Phase 3 trials, the last stage before seeking authorization or approval.

AstraZeneca is likely to seek US approval by January. Johnson & Johnson has said it will have efficacy data by January or February. Novavax is a little farther behind, but all of these companies will also be producing vaccines while testing goes on and might be adding to the count.
