Data from the US Centers for Disease Control and Prevention (CDC) show that delta strains appear to be twice as contagious compared to earlier strains.

The CDC states that “delta strains Among these, there are those who have been fully vaccinated, including those that … can infect others.”

However, the CDC points out that those who are vaccinated seem to transmit the disease for a shorter period of time than those who are not vaccinated. To that end, President Joe Biden urged people to vaccinate, saying it is “the best way to protect us from new mutants”.

The latest analysis of PHE indicates that a full dose of the coronavirus vaccine is effective in preventing hospitalization.

Another study in the UK indicates that Although the immunity obtained from 2 doses of the COVID-19 vaccine begins to decline over time. But the vaccine is still highly effective in preventing serious hospitalizations and death from delta strains.

More than 47.9 million people aged 16 and over in the UK have received their first dose of coronavirus vaccine, or about 88% of the population. Meanwhile, 42 million people, or about 78%, are fully vaccinated.
