New SARS-CoV-2 variants identified around the world could have an impact on current vaccination programmes. What is the latest evidence on the effectiveness of the COVID-19 vaccines used in the UK on new variants? How quickly can these vaccines be updated and approved? What alternative strategies can be used?

COVID-19 vaccine roll-out started in the UK on 8 December 2020. Results from Phase 3 clinical trials have been published for all the vaccines approved for use in the UK. But how does the performance of vaccines under real world conditions differ from clinical trial results? When will we able to observe the impacts of the COVID-19 vaccination programme?

What does it mean to reformulate food and drinks? How does it support healthier diets and lead to public health benefits? This POSTnote gives an overview of the most recent food and drink reformulation policies in the UK, the evidence on public health benefits and the effectiveness of different policies. It also explores challenges and opportunities for reformulation and describes some of the complementary approaches to improve public health.

With several potential vaccines approaching the end of clinical trials, a new focus is how they will be approved for general use. How does this process work? Who will receive the first COVID-19 vaccines when they become available in the UK? What are public attitudes towards a COVID-19 vaccine in the UK?

Vaccines are the most powerful tool against infectious diseases, and there are over 200 COVID-19 vaccines in development. Which COVID-19 vaccines are closer to the finish line? Which ones have been approved already for use in humans? When will a vaccine be available in the UK?

People’s behaviour has a major role in the success of test, trace and isolate programmes. Uncertainty about whether to report symptoms, low perceived risk of COVID-19 disease and concerns about the consequences of self-isolation are among the barriers to adherence. Has the Scientific Advisory Group for Emergencies looked at adherence to TTI? What evidence is there on people’s understanding and willingness to be tested, provide contact details and self-isolate? Is there anything that can be done to improve this?

Test, trace and isolate programmes across the UK are under pressure as COVID-19 cases rise in all age groups and demand for tests grows. Further pressure comes from people seeking tests because they have symptoms caused by other respiratory viruses but need a test in order to rule out COVID-19. The Scientific Advisory Group on Emergencies has described the impact of current test and tracing on the transmission of the virus as “marginal”. How does test and trace work and what are the current challenges limiting its effectiveness in reducing COVID-19 cases?

There is emerging evidence that COVID-19 affects many systems of the body, with patients reporting a wide range of symptoms. ‘Long-haulers’ are patients who experience ongoing COVID-19 symptoms for several months after infection. These include fatigue, difficulties in thinking, shortness of breath, chest pain, irregular or abnormal heart rhythm, and joint pain.

The UK Government secured early access to 340 million doses of six different COVID-19 vaccine candidates. It is still unknown whether any of them will be able to protect from SARS-CoV-2. In case of a successful vaccine candidate, supply may be initially constrained and therefore priority groups need to be defined.

The latest research suggests that antibodies can be detected in recovered patients for up to 2 to 3 months after symptoms. There's also emerging evidence for the role of T cells in the immune response. A better understanding of the immune response is vital if there is going to be a successful vaccine.

There are almost 150 coronavirus vaccine candidates under development. Only 19 of these are now being tested in humans. Many types of vaccines are rapidly progressing through clinical trials. Only two vaccine candidates have announced large scale Phase 3 trials, involving several thousands of people. Only one candidate has been approved for restricted human use. Measuring a reduction in COVID-19 levels is an obstacle for Phase 3 clinical trials, as they require a high infection rate among the tested population to prove vaccine efficacy. International agreements with countries where SARS-CoV-2 infection rates are still high are facilitating those trials. Future challenges in vaccine development include a better understanding of COVID-19 immunity and development of vaccination strategies.
