Young people are affected by Covid-19 and you might be at a higher risk than you think. If you are not vaccinated you are much more likely to get more serious symptoms and have to go into hospital – this includes young people. 

You are also at risk of long-Covid which can cause extreme tiredness, breathlessness and more; and stops you from doing normal everyday things like walking, as well as sports and going to the gym, or working, potentially for months or even longer. 


Getting the vaccine doesn’t just protect you against getting seriously ill, it also protects your family and friends. Anyone who doesn’t get vaccinated is more likely to catch and potentially pass on the virus to more vulnerable people, especially older people, even if they have been vaccinated. This could be a parent or grandparent, or a friend.  

The vaccines contain a fragment of genetic material which causes Covid-19 and triggers your body’s natural production of immune cells to protect you. The main ingredient is actually water, with preservatives and stabilisers added to keep them safe. None of the ingredients in the vaccine can cause you to get Covid-19 itself. 

The vaccines being used in the UK do not contain animal or foetal products, mercury or egg. These vaccines are halal, and suitable for vegans and vegetarians. The Pfizer vaccine does not contain any alcohol.

Yes, it’s safe, and it works. Billions of vaccines have been given worldwide. It is safe and effective, and reduces the spread of the virus so we can get back to normal. 

The NHS does not offer any vaccinations until it is safe to do so. The UK medicines regulator the Medicines and Healthcare products Regulatory Agency (MHRA) has approved these vaccines and there have been rigorous checks at every stage of their development and manufacturing process.  

Vaccinators are either existing NHS staff or people recruited by the NHS specifically for the programme. Everyone who gives the vaccine is fully trained and registered healthcare professionals provide clinical supervision.

There is no link between the Covid-19 vaccine and infertility. Not only is there no evidence that vaccines cause fertility problems in men or women, medical experts say there is no realistic way they could. Rumours circulating on social media are false.

There are reports from some women who have seen a change to their period cycle or symptoms after having their vaccination. Dr Pat O’Brien, Vice President at the Royal College of Obstetricians and Gynaecologists, said: "It’s important to remember these side effects are mild and should not deter women from having the vaccine when they are called. Many women will experience a temporary change in their periods from time to time during their lives.”

There nothing in the vaccine that can affect the fertility of women and there is no need to avoid pregnancy after Covid-19 vaccination. The Covid-19 vaccine also does not affect your likelihood of having a miscarriage.

Like all medicines, the Covid-19 vaccine can cause side effects but not everyone gets them and reports of serious side effects are very rare. The vast majority of side effects are mild, completely normal and disappear after a few days and include a sore arm, tiredness, fever, headache or feeling sick. You can take painkillers like paracetamol if you need to and if you’re worried you can call 111. You can’t catch Covid-19 from the vaccine.

Getting a vaccine is quick and easy. If you live in Tower Hamlets, Newham, Waltham Forest, City and Hackney, Barking and Dagenham, Redbridge or Havering and are within three months of your 18th birthday, you can book yourself in (either directly or using the national booking system), and sometimes walk-in, for your Covid-19 vaccination at over 50 vaccination centres in north east London. 

These vaccinations centres are spread across our communities in lots of easy to get to places like pharmacies, GP practices, libraries and shopping centres. You can get vaccinated whenever suits you including on weekends and in evenings, you usually won’t have to wait long and can expect to be in and out within half an hour. You don’t have to wait to be invited and you don’t need to bring any paperwork.

It is really important you have both doses of the vaccine to give you maximum protection from Covid-19. You should book your second jab eight weeks after your first dose.

You do not need to come with a parent/guardian.

Second doses are really important in giving you maximum protection from Covid-19.  You can book second doses from eight weeks after your first jabs.

You can walk in to some vaccination clinics and some you need to book. No proof of address or immigration status is required. If you book on the national booking service you will be asked for your name and date of birth. If you can’t book on the national booking service, information on where and how to get vaccinated at one of the many sites is here, many of which you can just walk into (including for over 16s):

If you booked through the National Booking Service then you should already have your second dose appointment. You can also log on to the system and manage your appointments. If you walked in or booked directly at a vaccination site you may have been given your second dose appointment, you can book on the National Booking Service, or visit here for information on sites across north east London and how to book them. Second vaccinations are not being offered sooner than 8 weeks after the first. 

There is no published data on the effects of alcohol on how well the body builds immunity. There is no evidence to suggest you need to avoid alcohol together, but drinking large quantities can suppress your immune system.

No. But you should get two doses to protect yourself, family, friends and community. 

If you have had Covid-19 then your body may have built up some natural immunity to the virus, however we don’t know how long this immunity lasts or if it fully protects you from catching Covid-19 again. It is likely that natural immunity won’t last as long as the immunity given to you by a vaccine, and there is no way of knowing if you have any protection. So, it is still very important to take up the offer of a Covid-19 vaccine when it becomes available to you.

It is normal for viruses to mutate, and some do so quicker and more effectively than others. Many of these mutations will not be significant or a cause for concern, but some like the current strain we are seeing in the UK can lead to things like higher transmission. The existing vaccines are still effective against it.

Over the long term it is common for virus mutations to be less severe. The vaccines can be rapidly adapted to meet these challenges, and in time it is likely there will be a range of vaccines like there are with the flu vaccine.

Everyone aged 5 (on or before 31 August 2022) and over can get a 1st and 2nd dose of the Covid-19 vaccine.

People aged 16 and over, and some children aged 12 to 15, can also get a booster dose.

People aged 5 and over who had a severely weakened immune system when they had their 1st or 2nd dose will be offered an additional primary dose (3rd dose) before any booster doses.

Some people, including those aged 50 years or over, those at higher risk or who are pregnant, and frontline health and social care workers, will be offered a seasonal booster (autumn booster).
