Covid-19 vaccination: Get shots before winter to avoid severe illness, Hong Kong experts warn people

Hong Kong scientists are urging city residents to get vaccinated before winter in the wake of a new study showing low temperatures exacerbate the severity of Covid-19.

The study, led by University of Hong Kong associate professor Jasper Chan Fuk-woo and top microbiologist Professor Yuen Kwok-yung, found that hamsters housed at low temperatures had their neutralising antibody responses suppressed and suffered more severe reactions to the disease.
