3 mins read


Health officials in the UK have administered close to 60 million jabs, giving most British adults at least a degree of protection from COVID-19. However, some people show hesitancy in receiving the vaccine with others having medical problems which stop them altogether. What are the four medical problems which may affect the use of the Covid vaccine?

According to the Mayo Clinic, the presence of certain medical problems may affect the use of this vaccine.

The health site warns a person should make sure they tell their doctor if they have any other medical problems, especially:

Bleeding problems (e.g., haemophilia)—Use with caution. May make this condition worse.

Illness with fever, severe

Infection, severe—Your doctor will decide if you should receive this vaccine.

Other conditions to be aware of

People with HIV and those with weakened immune systems due to other illnesses or medication might be at increased risk for severe COVID-19, said the Centers For Disease Control and Prevention (CDC).

The site added: “They may receive a COVID-19 vaccine. However, they should be aware of the limited safety data:

“Information about the safety of COVID-19 vaccines for people who have weakened immune systems in this group is not yet available.

“People with autoimmune conditions may receive a COVID-19 vaccine.

“However, they should be aware that no data are currently available on the safety of COVID-19 vaccines for people with autoimmune conditions.”

People with a history of “significant” allergic reactions should not have the new vaccine, regulators said on Wednesday morning.

The Medicines and Healthcare products Regulatory Agency (MHRA) said the advice applies to anyone who has had significant reactions to medicines, food or vaccines. It has not defined what a significant reaction is.

The new MHRA advice states: “Any person with a history of a significant allergic reaction to a vaccine, medicine or food (such as previous history of anaphylactoid reaction or those who have been advised to carry an adrenaline autoinjector) should not receive the Pfizer/BioNTech vaccine.”

According to the FDA’s vaccine fact sheet, typical side effects of the Pfizer-BioNTech vaccine include:

  • Tiredness
  • Headache
  • Fever
  • Chills
  • Muscle or joint pain
  • Nausea
  • Diarrhoea
  • Swollen lymph nodes
