A new study by Public Health England has reported that a single dose of a COVID-19 vaccine can reduce the transmission by half. This indicates, and brings hope, that the pandemic’s can in fact be put under control as those vaccinated are less likely to pass the virus onto someone else. The study, which involved more than 57,000 people living in 24,000 households who were contacts of a vaccinated person, shows that anyone who tests positive but has had at least one shot of AstraZeneca or Pfizer is around 38% and 49% less likely to transmit the virus.
Protection was seen from around 14 days after the jab was received, with the person’s age not being a factor that interferes. Further studies will indicate whether two full doses will slash the transmission even further. Health secretary Matt Hancock stated that this news ‘further reinforces that vaccines are the best way out of this pandemic.’
