- Coronavirus immunity might last as little as 6 months and as long as 12 months, a new study from Europe indicates.
- The conclusion is based on statistical data from a study that looked at human immunity against four coronaviruses that are responsible for the common cold.
- Determining the actual duration of COVID-19 immunity is a crucial detail for vaccination campaigns, concepts like herd immunity and “immunity passports,” as well as other official protocols meant to reduce the spread of the disease until treatment is widely available.
The world has come a long way in around 5 months of fighting a virus that had never challenged humans before. SARS-CoV-2 is the newest member of a coronavirus family that we’ve already trained ourselves to fight. Four other versions cause common colds, and the SARS and MERS coronaviruses were responsible for dangerous outbreaks in the past two decades. The novel strain is the most dangerous of them all considering what happened so far. More than 5.6 million people have been infected as of Tuesday morning, and over 351,000 people lost their lives so far. That’s a huge sacrifice the world had to make, but it wasn’t all in vain. The strict social distancing measures that most countries implemented have saved lives, stopped the spread of the novel coronavirus, and bought us all precious time. Doctors treating the disease and researchers were able to come up with viable therapies that helped save lives. More courses of treatment for COVID-19 are in testing, as well as brand new drugs that have been explicitly designed to boost the immune response against the novel virus. Separately, more than 100 drug makers are developing vaccine candidates, and several of them proved their worth in pre-clinical and clinical tests. It seems like it’s just a matter of time until the first viable vaccine is ready for mass inoculation.
But it’s at this point that we have to take into account one of the worst types of outcomes going forward. Vaccines should be effective or safe against COVID-19, but there’s a possibility that coronavirus immunity might be shored-lived, regardless of whether it’s obtained by surviving the disease or via immunization. Now, a new study tells us that might indeed be a possibility for SARS-CoV-2, and immunity might last as little as 6 months.
