Some American states who have ever wanted to get a lot of doses of Covid-19 vaccine as possible, now they are overcasting vaccines when he is larger than the demand.

Many states are thinking of new and creative ways to vaccinate people who are difficult to access or hesitate to vaccinate, although there are still 43% of Americans who are not vaccinated.

Of the 329 million vaccine doses transferred to the states, about 257 million doses were injected, according to the American Disease Control and Prevention Center (CDC).

The federal government distributes vaccines to population-based areas.

The situation of translation in many places in the US has improved.

However, some public health officials are concerned that reduced vaccination needs can lead to long-term problems such as the number of deaths and hospitalizations do not decrease.

"If you can stand watching the relatives die. But I can't stand it," Justice said.

"I can't stand these masks," he said and threw it on the table.

Last week, Governor Arkansas Asa Hutchinson aims to vaccinate 50% of the state's population in the next 90 days.

Recently, more and less people inject vaccines in many states.

Jennifer Nuzzo, the leading epidemiologist from the NCOV Johns Hopkins test initiative, said that in many states, the most accessible groups were vaccinated.

The remaining number is mainly divided into three groups: those who want to vaccinate but are not possible, people hesitate on vaccines or delay vaccines, who oppose vaccines for religious reasons, philosophy or news

"Although I think the need is declining, I think there are still people who want to get vaccinated but can't," Nuzzo said.

In those groups there are older people who cannot leave home, cannot go to the vaccine point, who cannot set an examination for technology problems, some parents are busy working or people living in the community

Many local governments and states try to fix the problem by building mobile clinics and eliminating pre-scheduling requests at mass vaccinations.

NUZZO said the effort to approach these groups could be like a campaign "promoting voters to vote".

The second type is that people can doubt the vaccine or are waiting to see how the situation before vaccination.

However, Nuzzo thinks these people may also gradually be doubted about vaccines.

The third group is the complete opposer to the vaccine, especially those who believe in false information and conspiracy theory.

Officials said that promoting the freedom that people who have been vaccinated can be effective way to encourage more vaccines.

The US was injecting about 1.98 million doses of vaccines a day, down from 3.38 million on April 13.

NUZZO said that if the vaccination rate continues to decline, local communities can record significant outbreaks.

"Many people have lost their lives," she said, "and that now can be stopped."
