The current second wave of coronavirus it may not be the last. Many experts had predicted this second wave and others have long been talking about a virus that we will have to live with at least for all of 2021. But, therefore, it could Is there also a third wave? So it seems.

The progress of the pandemic will be influenced by several factors, first of all, of course, the vaccine. An article in the magazine Nature explains: “Many vaccines provide protection for decades, such as measles or polio, while others, such as whooping cough and flu, disappear over time. Also, some viral infections induce long-lasting immunity while others induce a more transient response. ‘ The solution for the end of the epidemic, therefore, may not be in the vaccine, as other experts have been saying for some time.
Another influencing element the trend of the pandemic is immunity. «The total incidence of Sars-Cov-2 until 2025 – underlines a group of experts from Harvard University in a work published last May in Science – It will depend fundamentally on the duration of immunity ». Considered a hypothesis of short-term immunity, the researchers believe that there may be multiple waves annually. If, on the contrary, it is proven that the covid leaves a perennial immunity at the end of 2021, the virus could disappear, but for now there is no certainty about it.
Another factor is prevention. Therefore, compliance with the anti-contagion regulations. The presence of a third wave is therefore not certain, but it cannot be excluded either. It is almost certain, all the experts say, that we will have to deal with covid at least for all of 2021, even if it is not known to what extent.
