- A pair of new coronavirus vaccine studies show that a single dose produces a strong immune response in COVID-19 survivors, indicating that authorities should consider a protocol change for people who had the illness.
- One study showed that a single vaccine shot is enough to increase the number of antibodies by a thousandfold, to a level that would neutralize the South African mutation and even the SARS virus from 2013.
- A separate study proved the same strong immune response in COVID-19 survivors after just one shot.
- In early February, two other studies also showed that COVID-19 survivors develop a strong immune response after one vaccine dose, indicating that an immunization protocol change might be needed.
The number of new COVID-19 cases has been dropping dramatically in the past few weeks. However, hundreds of thousands of people are still diagnosed every day, and tens of thousands continue to die on a daily basis from coronavirus complications. Vaccination campaigns have reached a notable milestone, with more than 200 million people having received at least one vaccine dose so far. Over 35.7 million people have completed the two-dose regimen. Despite those developments, the pandemic is still a worldwide concern, especially considering the major mutations discovered in late 2020 and early 2021. The novel coronavirus undergoes genetic changes just like any other infectious microorganism, and some of the new mutants are more resistant to vaccines. Mutations could fuel additional waves and further delay the end of the pandemic, especially if those genetic changes can evade vaccine protection.
Recent developments from Pfizer and BioNTech will allow the two companies to ramp up vaccine supply. Their vaccine can also be stored at higher temperatures, which could extend the reach of vaccination campaigns. Furthermore, drugs like Johnson & Johnson’s candidate could soon be authorized for emergency use, increasing the pool of vaccine candidates that can prevent severe COVID-19. But there may now be an additional development that will further increase vaccine availability. New studies indicate that coronavirus vaccine protocols may be in need of a key change that would make more vaccines available to more people.
