Johnson and Johnson COVID-19 Vaccine

Sunday, February 28, 2021, the CDC recommended and endorsed the Johnson and Johnson COVID-19 vaccine’s safety and effectiveness. Furthermore, it authorized the emergency use of the vaccine for people age 18 and older. Consequently, CNN reports today, “US begins distribution of a third Covid-19 vaccine.”

COVID-19 Vaccinations in US

Up to 4 million doses of the Johnson and Johnson COVID-19 vaccine are ready to roll out this week. This new COVID-19 vaccine only requires one dose. Whereas the other COVID-19 vaccines (Pfizer and Moderna) require two doses. 

In other words, you only need to get a single shot in the arm with this new COVID-19 vaccine. However, Pfizer and Moderna COVID-19 vaccines require three-week immunity (waiting) period between shots. Thus, Pfizer and Moderna vaccines take twice as long for a person to become fully vaccinated. 

US COVID-19 Vaccinations

The United States has administered 75 million COVID-19 vaccinations from December 14, 2020, to February 28, 2021. However, the percentage of Americans fully vaccinated is only 7.6%. To be fully vaccinated, you have to receive two shots of either Pfizer or Moderna COVID-19 vaccines.

Most of these 75 million vaccinated Americans have received only one shot. Furthermore, some people who had their first shot may choose not to get a second shot. Since the new Johnson and Johnson COVID-19 vaccine only requires a single shot, we can expect the rate of fully vaccinated Americans to increase much faster. In other words, the pace to end the COVID-19 pandemic will quicken starting in March 2021.

COVID-19 Vaccine Effectiveness

The two-shot COVID-19 vaccines (Pfizer and Moderna) are about 95% effective. However, the one-shot Johnson and Johnson vaccine is only 72% effective against moderate to severe COVID-19 infection. Furthermore, it’s nearly 86% effective against severe forms of the disease.

Vaccine Storage and Transport

Unlike the Pfizer and Moderna vaccines that require subzero storage and transport, the Johnson and Johnson vaccine only requires refrigeration. It’s much easier to transport and store the new Johnson and Johnson COVID-19 vaccine. This difference will make the new vaccine widely available to many communities, including mobile sites.
