A "worry - free" summer, that's what people vaccinated against the new corona virus were supposed to spend a summer, but the emergence of a highly contagious delta mutant ruined these expectations.

Although the vaccines currently available are still remarkably effective against COFID-19 and its mutants, the new recommendations for pollinators have left many people very confused.

While new research shows that vaccinated people can be infected and infected, it is important to remember that such cases remain rare, and that it is the non-pollinators who become infected and spread the virus more widely.

Greg Jonsalves, assistant professor of epidemiology at the Yale School of Public Health in the United States, said: "If you're vaccinated, you've done the most important thing for you, your family and your friends to keep everyone safe," he said, adding, "There's more freedom for people who are vaccinated. The now popular idea that nothing has changed despite vaccination campaigns is not true. "

The Centers for Disease Control and Prevention in America (CDC) advises the wearing of muzzles in areas with high HIV prevalence (50 cases per 100,000 people).

Experts say that the pollinator must take into account the area in which he or she lives and the number of infected and vaccinated in order to decide whether or not to wear the muzzle, noting that it must continue to be worn in the event of a human being in the midst of a crowd.

It is noted that aircraft are usually well ventilated and not a major source of outbreak, but taking precautions must remain at the top of your priorities. Airlines are still asking passengers to wear masks and commit to social divergence in airport facilities.

Health professionals indicate that travel is safe as long as the passenger takes his or her stand-by action.

With regard to the safety of buses, subways and trains, most buses, trains and subways still require everyone to wear masks, thereby reducing the risk.

Vaccinated people are well protected, but the risk of HIV infection increases the longer the journey and the more congested the means of transport.

It also states that although it is generally safe to hug vaccinated people and spend time with them without a mask, as the variant delta spreads, the risk of close contact with older or vulnerable people who are more vulnerable to corona complications increases, even if vaccinated.

When families plan to visit a relative at greater risk, it's good to take the necessary precautions.
