Johnson & Johnson (J&J) just announced that a booster shot of their COVID-19 vaccine has generated promising immune response in early stage clinical trials.

Johnson & Johnson made the announcement in a press release issued early Wednesday morning about their initial research of a vaccine booster shot.

The study found that those who received a booster shot of the vaccine — as part of the trial — generated virus-fighting antibodies "nine fold higher" than those seen after the initial dose.

The news, of course, is quite promising.

But today's announcement did not mention anything about the effects a booster shot may have in helping to fight the delta variant of COVID-19.

Johnson & Johnson says they're engaging with the FDA and other health authorities to discuss the possibility of a booster shot.

The CDC has previously said that those who received the J&J vaccine will probably need a booster dose, but they say that there is not enough data to formally recommend it at this time.

LOOK: Here are the 50 best beach towns in America

Every beach town has its share of pluses and minuses, which got us thinking about what makes a beach town the best one to live in. To find out, Stacker consulted data from WalletHub, released June 17, 2020, that compares U.S. beach towns. Ratings are based on six categories: affordability, weather, safety, economy, education and health, and quality of life. The cities ranged in population from 10,000 to 150,000, but they had to have at least one local beach listed on TripAdvisor. Read the full methodology here. From those rankings, we selected the top 50. Readers who live in California and Florida will be unsurprised to learn that many of towns featured here are in one of those two states.
