More vaccines coming

Bring ’em.

The Food and Drug Administration approved Johnson & Johnson’s COVID-19 vaccine on Saturday for use in the U.S., the third vaccine to be approved since the pandemic began.

Texas could initially receive more than 200,000 doses, according to the Texas Department of State Health Services, but the agency hasn’t received a timeline for when they would arrive. The company has said it plans to ship 20 million shots in the U.S. by the end of March and an additional 80 million doses before the end of June.

Texas received about 1.5 million vaccine doses by Pfizer and Moderna this week, including doses that had been undelivered earlier in the month because of the winter storm.

Unlike those vaccines, Johnson & Johnson’s formulation is the first to only require one dose, and it can be stored at regular refrigeration temperatures. The others require two doses, and Pfizer doses must be stored at below-freezing temperatures.

Five million vaccine doses have been administered overall in Texas as of Feb. 25. That equals about 5.8% of the state’s population — a long way from the 70% to 80% that experts estimate is necessary to achieve herd immunity. It would require nearly 100% of adults to be vaccinated to reach those figures, according to census numbers.

Scientists are still monitoring how well vaccines prevent the spread of the coronavirus, and health officials advise those who are vaccinated to continue wearing masks, social distance and follow other COVID-19 safety guidelines.

Hopefully, the J&J vaccine will really kick this up a notch, since it only requires the one shot. But as always, it’s first a matter of supply, and just having another supplier should help. If J&J is delivering 80 million doses nationally by the end of June, that should be six or seven million for Texas. It’s all about the numbers.
