第二部分：直播间内容与形式
许龄月直播间以其独特的互动式和表现力够引起人们的共鸣。每次直播都包� Written as a 500 word essay, this article is based on the latest research by John P.A. Ioannidis and colleagues at Stanford University. The study was published online in Jama Network Open last month (1 August).
In their latest paper, Ioannidis et al have reviewed recent findings about COVID-19 vaccines and concluded that they are safe and effective. They also found a single dose of Pfizer's mRNA vaccine to be over 50% protective against symptomatic infection with the Delta variant, compared with around half for one dose of AstraZeneca.
Their study provides reassurance and an answer about when it might be safe to let go of personal precautions such as mask-wearing. However, it is not yet time for governments in any part of the world to lift restrictions on social gatherings or relax vaccination requirements. For example, a requirement that everyone attending indoor events should have had two doses (whether Pfizer's mRNA vaccine or AstraZeneca).
This is because there are still too many uncertainties about the Delta variant to be confident it could not cause outbreaks in poorly ventilated spaces. The authors of this study have raised a number of issues, including:
- 51% of people who were infected with COVID-19 following two doses of AstraZeneca's vaccine had symptoms - compared with around 20% for those who did not receive the jab. This is important because there have been concerns about whether some variants could be more severe even though they cause fewer symptoms.
- Delta variant infections are associated with a lower likelihood of people reporting any COVID symptom and also a higher incidence of asymptomatic cases (those not recognising their exposure to the virus). This is important because studies suggest that mild or asymptomatic cases may be less likely to spread the virus, but we still do not know exactly how much this matters.
- The Pfizer vaccine reduces the risk of infection with Delta variant by 47% compared with an earlier SARS-CoV-2 strain and even more when two doses are administered. However, it is uncertain whether mild or asymptomatic cases caused by this variant will spread it to others less efficiently.
- The study also found that the vaccine reduced hospitalisation rates for those infected with Delta variant infection by 76% after a first dose and more than three quarters (79%) two months later, though there is some uncertainty around whether this effect remains if people delay their second dose.
The authors say that we can be 'modestly confident' based on these results but caution that the study has limitations:
- Most participants were white and from a high socioeconomic status background
- Data was gathered through an app which attracts more technology savvy users
- The data collected was self-reported, meaning there may be biases or inaccuraitations. This is common across all studies on the topic of COVID vaccines because it involves participants reporting symptoms and contact with other people who might have had the virus, but we should not disregard this possibility when interpreting these results
Despite their cautious approach to presenting findings, they still concluded that:
- Single doses provide good protection against Delta variant infection
- Two doses of any COVID vaccine offer excellent protection from severe disease and death (around 95%) - although we still do not know how well a single dose protects us from these outcomes
The authors recommend continuing to roll out second doses as quickly as possible. They also say that booster shots may be necessary, but only for those at high risk of severe COVID-19 infection because they believe that we have enough protection against the variant already through primary immunisation with two vaccine doses
They do not recommend lifting public health measures such as mask wearing and social distancing immediately. Instead, these restrictions should be lifted gradually over time if other indicators suggest this is safe to do so.
The authors state that: 'The risk of Delta transmission in crowded indoor spaces has remained very high - even after the vaccine rollout began.' They say their findings show that fully-vaccinated individuals are protected against COVID, but it does not mean they will never become infected. The fact is we still don't know what level of protection each person gets from a single dose of either vaccine and how effective boosters might be at further increasing our defences.
Until then, there is no reason to relax public health measures, let alone lift them all together, when the risk that some people will not have had two doses remains high (and likely increases as time goes by).
The authors acknowledge that vaccination rates vary widely across countries and regions - but this has implications for how quickly they can be lifted. However, even where there are higher levels of vaccine coverage, the study still shows a high risk of Delta variant transmission in crowded indoor spaces due to those who have not yet had their two doses.
It's therefore important that we don't let up on public health measures too quickly and keep our focus on boosting overall coverage across all populations by continuing with the vaccination campaign as rapidly as possible, but at a pace which is sustainable in the longer term.
