The forgotten Covid jab which may have NO uncomfortable side effects on youngsters

The Novavax Covid vaccine, which can be simply days away from approval within the UK, might be safer for kids than the UK’s present jabs, consultants say. 

It’s hoped that the US shot — which makes use of tried and true vaccine expertise and is manufactured in Teeside — may scale back hesitancy and increase uptake in youngsters. 

The UK Authorities already has 60million doses of Novavax on order and trials present it’s 96 per cent efficient in adults.

However crucially it was proven to trigger much less uncomfortable side effects in comparison with these triggered by Pfizer, Moderna and even AstraZeneca’s vaccines. 

The vaccine, recognized scientifically as NVX-CoV2373, could be the primary protein-based jab accepted within the UK, if given the inexperienced gentle.

Protein-based jabs are already given to youngsters to guard in opposition to the flu, meningitis and hepatitis. 

Consultants advised MailOnline approval of the vaccine may pave the way in which for the jab being rolled out to youngsters, in addition to encouraging the vaccine-hesitant to return ahead.  

Remaining research information was submitted to the Medicines and Healthcare Merchandise Regulatory Company (MHRA) final month and approval is predicted in days.

Different injections in opposition to Covid already accepted within the UK are both viral vector vaccines which are constructed from a standard chilly virus (AstraZeneca), or an mRNA vaccine constructed from enzymes (Pfizer and Moderna).

Novavax’s incorporates proteins that mimic the spikes on the coronavirus, inflicting the physique to supply antibodies to struggle the an infection.

If the physique encounters coronavirus sooner or later, the physique is primed to fend it off.

The injection is run in two doses 21 days aside. Not like the opposite jabs that must be saved at ultra-cold temperatures, Novavax may be saved in a standard fridge for as much as three months. 


How does the vaccine work?

The Novavax vaccine works like different vaccines by educating the immune system to make antibodies to the coronavirus spike protein.

Researchers inserted a modified gene right into a virus, referred to as a baculovirus, and allowed it to contaminate insect cells.

Spike proteins from these cells had been then assembled into nanoparticles which, whereas they seem like coronavirus, can’t replicate or trigger Covid-19. These nanoparticles are then injected into the physique through the vaccine the place the immune system mounts an antibody response.

If the physique encounters coronavirus sooner or later, the physique is primed to fend it off. The vaccine is given as two doses.

Are there benefits of the Novavax vaccine?

Sure. Whereas the jabs from Pfizer/BioNTech and Moderna must be saved at ultra-low temperatures, the Novavax jab is secure for as much as three months in a standard fridge.

How efficient is the vaccine?

In accordance with outcomes of part III trials, the jab provides one hundred pc safety in opposition to extreme illness, together with all hospital admission and demise.

It’s 86 % efficient in opposition to the Alpha (Kent) variant and one hundred pc efficient in stopping instances brought on by the unique pressure of the coronavirus. 

Has the Novavax vaccine been accepted?

Not but. The UK’s Medicines and Healthcare Merchandise Regulatory Company is reviewing information on the jab.

Within the US, the info can be examined by regulators on the Meals and Drug Administration after Novavax applies for Emergency Use Authorization.

And part three by Maryland-based Novavax of greater than 15,000 folks within the UK discovered the jab had an efficacy price of 96.4 in opposition to gentle, average and extreme illness brought on by the unique coronavirus pressure. 

In the meantime, a trial of the vaccine on 30,000 folks within the US and Mexico discovered it gave 100 per cent safety in opposition to average and extreme illness.  

Protein vaccines already in use embody the hepatitis B and meningitis jabs, that are routinely given to newborns.

The vaccines presently used within the UK have saved hundreds of lives, whereas health chiefs mentioned the rollout to youngsters will assist hold them in class school rooms.

Greater than 1million pupils had been pressured to overlook college in a single week in England in July because of the virus.

However one in 10 over-18s in England are but to have their first dose by November 18.

And uptake amongst 12 to 15-year-olds was simply 38.4 per cent, whereas 63.9 per cent of 16 to 17-year-olds had had a primary dose. 

The small danger the virus poses to youngsters, in addition to issues about myocarditis after vaccination, are considered components behind the low uptake.

Information from the Joint Committee on Vaccination and Immunisation reveals as much as one in 56,000 12 to 15-year-olds will get myocarditis after their first Covid jab.

However the price jumps to as many as one in 23,000 instances after second doses, so the cohort presently solely receives a single jab. 

And the AstraZeneca jab has been linked with blood clots in youthful folks, which pushed well being chiefs to restrict the usage of the Oxford-made injection to the over-40s.

However Novavax trial information reveals the jab solely triggered gentle and short-lived uncomfortable side effects, with no severe antagonistic results.

Its research didn’t embody under-18s and was not sufficiently big to select up on both of the very uncommon uncomfortable side effects, however discovered that adults total tolerated the jab nicely, with reported uncomfortable side effects being gentle and short-lived. 

Novavax is presently trialling its jab on 2,200 12 to 17-year-olds within the US.

The opposite Covid vaccines additionally confirmed comparable outcomes at a trial stage, however consultants are hopeful that the Novavax findings will maintain robust if the jab is rolled out within the inhabitants. 

Professor Neil Mabbott, chair in immunopathology on the College of Edinburgh, advised MailOnlinethe as a result of the jab has fewer uncomfortable side effects than the present crop of injections used within the UK, Novavax ‘may provide another technique to be used in youngsters which may keep away from the very low danger of creating probably extreme uncomfortable side effects’.

And comparable protein-based expertise has been used for years in routine childhood vaccines, he mentioned. 

Professor Mabbott mentioned: ‘This may increasingly assist to offer some security reassurance to those that till now have been hesitant about coming ahead to have their very own Covid vaccine. 

‘This may increasingly additionally assist to alleviate the issues mother and father could have about the usage of these vaccines in youngsters. This might have a constructive affect on vaccine uptake.’

He added: ‘You will need to point out that severe side-effects equivalent to blood clots and coronary heart irritation following vaccination with the mRNA-based (Pfizer or Moderna) and adenovirus-based (AstraZeneca or Janssen) Covid vaccines have been very uncommon. 

The UK has ordered 60million doses of the Novavax vaccine. In total, Britain has ordered more than 400million doses of eight difference vaccines, but only four have so far been approved by the MHRA: AstraZeneca, Pfizer, Moderna and Janssen

‘Use of those vaccines in defending in opposition to severe illness or demise following coronavirus an infection continues to outweigh the very low danger of uncomfortable side effects.’

However he famous that an approval of the Novavax vaccine ‘may have a constructive affect on vaccine uptake by encouraging as many individuals as doable to be totally vaccinated in opposition to the coronavirus’. 

The MHRA decides whether or not to approve any vaccine primarily based on security, high quality and effectiveness information.

The company advised MailOnline it couldn’t advise when it expects to challenge a choice because of industrial confidentiality. 

And Novavax advised MailOnline ‘the timeline is within the arms of the regulatory businesses’.

Dr Michael Head, a senior analysis fellow in international well being on the College of Southampton, advised MailOnline: ‘A brand new vaccine approval can be good news.

‘The information publicly accessible on Novavax seems very promising, each when it comes to effectiveness, however importantly additionally with security.

‘The prevailing COVID-19 vaccines are glorious. Nonetheless, if additional folks may be persuaded to turn into vaccinated as a result of Novavax is a ‘tried and examined’ method to vaccine growth, then that may solely be factor.’

Dr Alexander Edwards, an affiliate professor in biomedical expertise on the College of Studying, advised MailOnline the Novavax vaccine is ‘tremendously thrilling’ as a result of it’s made in a different way to the opposite Covid jabs used within the UK and incorporates very totally different elements. 

He mentioned: ‘The extra totally different instruments now we have to cut back the hurt brought on by Covid, the higher. 

‘The entire vaccines stimulate antibody responses that successfully neutralise the virus, stopping it rising in our bodies- and an important advantage of this can be a actually spectacular discount within the danger of extreme illness. 

‘But additionally it helps sluggish the unfold, so getting vaccinated protects you but additionally helps others.’
