Questions and Answers about the AstraZeneca Covid-19 Vaccine

Should I really be worried about blood clots?

The AstraZeneca vaccine has been given to many millions of people across the world (over 10 million in the UK). A few of these people have suffered from blood clots after receiving the vaccine but no causal relationship has been found and the number of people affected is not above what we would expect in the general population in people who did not receive the vaccine.

How safe is the vaccine?

The clinical trials in which the vaccine was tested showed it was very safe, with a very low level of serious side effects and this has been confirmed subsequently in the wider use of the vaccine in the UK and elsewhere.

Why are so many countries suspending it?

When a possible side effect is linked to a drug or vaccine, some countries will temporarily suspend use of the product until this has been investigated further. This does not mean that the vaccine is unsafe and we would expect further review of the data to confirm its safety. Now that the European Medicines Agency has completed its review and concluded that the vaccine is safe, with the benefits far outweighing the risks, countries that temporarily suspended using the vaccine have begun to use the vaccine again.

Can I reduce the risk of a blood clot by taking an aspirin?

It’s probably not advisable to use aspirin in this way because no link between blood clots and the vaccine has been confirmed and there is a small risk of suffering a serious stomach bleed after taking aspirin.

What are the other possible side effects of the vaccine?

The most common side effects of the vaccine are pain and tenderness at the injection site, headache, tiredness, generalised muscle pain, shivering and a fever. These side effects usually resolve within a few days.

Does your age affect the likelihood of side effects? (For instance, do younger people feel worse because their immune systems are better?)

Side effects can occur at all ages but tend to be less common in older people. This is thought to be because the immune system gradually weakens with age, which also leaves older people more susceptible to infection.

Won’t I still be protected if I refuse the vaccine, because so many other people have had it?

It’s important that as many people as possible receive the vaccine. If a large number of people are not vaccinated, we will continue to see outbreaks of Covid-19, with some people suffering a serious infection that could result in hospital admission or death. The vaccine is not 100% effective and children are not currently being immunised, so there will be many people in the population who can still become infected.

What’s the down side of not having the vaccine?

If you don’t receive the vaccine, you are at much higher risk of contracting a Covid-19 infection. These infections can be serious, leading to long-term complications and death in many people. You may also infect others, including elderly relatives who may be at high-risk of serious illness. Furthermore, the more people who receive the vaccine, the more likely we are to an end to the pandemic and the lockdown measures it has led to.

MPH Student Presentations on the NHS Care.Data Programme

As part of a session on primary care data in the Health Informatics module on the Imperial Master of Public Health Programme, I asked students to work in two groups to present arguments for and against the NHS Care.Data programme. Care.Data is an NHS programme that will extract data from the medical records held by general practitioners (GPs) in England. The Care.Data programme takes advantage of the very high level of use of electronic medical records by GPs in England. After extraction, data will be uploaded to the NHS Health and Social Care Information Centre (HSCIC). The data will then be used for functions such as health care planning, monitoring disease patterns and research. The programme has been controversial with proponents arguing that the programme will bring many benefits for the NHS and the population of England; and opponents arguing it is a major breach of privacy. You can view the two presentations to help inform you further about these arguments: Arguments for th

How can we work successfully across the health and care system to make a success of Pharmacy First?

Pharmacies in England to begin treating patients for seven common conditions. How can we work successfully across the health and care system to make a success of Pharmacy First? 1. The Pharmacy First scheme aims to provide convenient access to healthcare through community pharmacies. Patients with minor ailments or common conditions can seek advice and treatment directly from their local pharmacy instead of visiting a general practice, urgent care centre or emergency department. The conditions covered by the scheme may vary depending on local funding arrangements and participation of pharmacies.  2, A potential problem with Pharmacy First is pharmacists misdiagnosing a patient's condition. It may also lead to delays in patients seeing doctors when medical assessment is needed. To mitigate these risks, appropriate safeguards and referral pathways should be established, ensuring timely medical assessment when necessary. The scheme will also increase the workload of pharmacies, thereb

Example ADHD Referral Letter

Dear Dr, I am writing to refer a 28-year-old male patient of mine, Mr [Patient's Name], for assessment for the diagnosis and treatment of Attention Deficit Hyperactivity Disorder (ADHD). After a thorough clinical assessment, I believe that Mr. [Patient's Name] meets the criteria for adult ADHD as outlined in NHS guidance for primary care teams in SE London. Mr [Patient's Name] has been under my care for XX years and, during this time, he reports several symptoms (greater than five symptoms in total) consistent with ADHD in adults that have been present for more than six months. These symptoms include difficulties in focusing, following through on tasks, hyperactivity, forgetfulness, impulsiveness, restlessness, and irritability. Mr [Patient's Name] also reports being easily distracted, struggling with time management, organisation, and completing tasks efficiently. Many of Mr [Patient's Name]'s symptoms have been present since he was under 12 years old; and have
