20 states have already reached 70% vaccination rate

• 20 states have given at least one dose of a vaccine to at least 70% of their adult population.
• President Joe Biden had a goal of vaccinating 70% of adults across the country by July 4.
• Vermont has the highest vaccination rate with 85.3%, The New York Times reported.

While the whole country won't meet President Joe Biden's July 4 goal for vaccinating 70% of their adult population, twenty states have given at least one dose of a vaccine to at least 70% of their population, The New York Times reported.

Washington, D.C., Puerto Rico, and Guam have also reached the 70% mark.

The states that reached at least 70% are mostly in the Northeast and Mid-Atlantic region. Vermont has the highest vaccination rate with 85.3%, followed by Hawaii with 83.5%. Massachusetts, Connecticut, Maine, New Mexico, New Jersey, Rhode Island, Pennsylvania, Maryland, California, Washington, New Hampshire, New York, Illinois, Virginia, Delaware, and Minnesota, Colorado, and Oregon have also reached the 70% mark.

The vast majority of states with the least vaccination rate are in the South. Even as vaccination rates are high in some parts of the country, those with the least amount of their population vaccinated are at risk of a surge in cases as the more transmissible Delta variant - which originated in India - becomes a growing concern.

Experts told Insider's Aria Bendix and Joanna Lin Su that they ideally want communities to have at least a 75% vaccination rate so the virus is less able to spread from person to person.

More than 66.8% of American adults over the age of 18 are fully vaccinated against COVID-19, data from the Centers for Disease Control shows.

Overall, 54.7% of the population is fully vaccinated.
