As the search for an effective measure against COVID-19 continues at an unprecedented pace, scientists are debating the relative merits of vaccines and antibody therapy. What are these two options, and which would be better? Glenmed Professional Healthcare Solutions considers the two options.

The Pros and Cons Of Vaccines Vs Antibody Therapy

Vaccines and antibody therapy are the two most promising measures being developed to fight against the COVID-19 pandemic. These two therapies have a lot in common, but there are also several distinctions between them. Let’s compare the two and see what medical professionals are saying about their relative merits. Take a look at our blog for more information on the medical industry and medical technology.


Vaccines work by introducing a non-infectious piece of the virus into your body. The idea is that your immune system will recognise the virus fragment and develop antibodies against it. In this way, a vaccine ‘trains’ the immune system to protect the body against any future COVID-19 infection. It takes effect one to two weeks after vaccination, and can last for a lifetime, depending on the vaccine.

Antibody Therapy

Antibody therapy introduces a molecule into the system that then binds and neutralises the virus. It is a direct and immediate measure to fight the infection. It goes to work instantly and lasts for a limited period of time – weeks to months.

Which Is Better?

This is not necessarily an ‘either/or’ proposition. An antibody drawn from someone who has survived COVID-19 can immediately treat an existing infection, while a vaccine can train the system to defend itself against future infections. A vaccine is needed to develop general immunity against the virus, but antibody therapy can help those who are already infected. With both options available to us, we can effectively fight the pandemic.
