Will vaccines help NSW get out of lockdown?

August 2, 2021 Coronavirus (Covid-19), Headline News No Comments

The big question for NSW and Sydney right now is when it will come out of lockdown with the other being whether vaccines will it get out of lockdown.

Christine Jenkins a Professor of Respiratory Medicine at UNSW Sydney and head of the Respiratory Group at the George Institute for Global Health, says, “Vaccinations will make a dramatic difference, but they cannot do it instantly”, adding, “It takes approximately three weeks for a person’s antibody levels to rise to a level that reduces the risk of symptomatic infection with SARS-CoV-2 by about 50 per cent after the first dose, and a further two to three weeks after the second dose to approach the maximum benefit from two doses”.

She said that “Having said this, the effects of vaccination commence early so even after one dose, there are benefits in reducing transmission to close contacts and households”, adding, “This is most important if household members are working in high-risk settings and potentially bringing the infection back home” adding, “Reductions in transmission rates in households can be seen as soon as 14 days after vaccination, and at 21 days the risk is reduced by 40-50 per cent, approximately the same for both AstraZeneca and Pfizer”.

Professor Jenkins said, “This was shown recently in a comprehensive study analysing data in over a million vaccinated people compared to unvaccinated people in the UK,” adding, “This same study showed that contacts of vaccinated cases have lower odds of being secondary cases if the index case was vaccinated 14 days or more before testing positive”, and “These data suggest that the sooner people are vaccinated, the sooner they are protected themselves and the sooner their close contacts are protected”.

Professor Jenkins concluded saying, “Vaccination is therefore likely to reduce the probability of transmitting the infection as early as 14 days”, adding, “Hence it can reduce our numbers and help shorten the length of the lockdown as well as reduce the probability that we will need further lockdowns”, and “The sooner a high proportion of the population is vaccinated, the sooner we can return to the freedom we crave.”
