COVID-19 immunity could last for 5 months, but risk exists: Study
A study by Public Health England found that COVID-19 immunity could last for at least 5 months, but people can still spread it. Among the 6,614 participants in the study, only 44 people were reinfected with the virus. Experts cautioned that the findings mean people who contracted the virus in early 2020 may now be vulnerable to catching it again.
