The rate of vaccination has been slow, while we are at a very bad place with Covid hospitalizations and deaths. Only 1.8% of America has been vaccinated so far. The table below and the link to the article below show how many people have been vaccinated by State and territory.
Some of the problem is likely the lack of personnel to administer the shots. Many of the hospitals and health departments that are administering the vaccines are overwhelmed with the sick. This may be the problem in California and Arizona, which have a lower than average rate of vaccination.
The US should mobilize our military to help the States administer the vaccine. We have very experienced medical people who can work very hard and long hours to help administer the vaccine. Regular troops could help with administration and logistics. The States should be contacted to find out if they need personnel and then provide that where possible.
