There are many problems with #Covaxin #vaccine, contrary to the article tweeted multiple times at me.
In April @WHO blocked it because…

Exportation from India was halted on April 2 after @WHO discovered manufacturing contamination…
An Indian study found 2-dose #Covaxin only 47% effective against #SARSCoV2 despite manufacturer claim of 93%.…
#Covaxin can be stored at 47 degrees F, unlike the super-cold required for mRNA vaccines. That's a big plus.
Still, head-on-head independent comparisons of #COVID19 #vaccines against #Omicron found the Bharat-made Covaxin performed poorly.…

The #WHO on April 2 issued a statement saying the supply of #Covaxin to UN agencies had been suspended due to "deficiencies in good manufacturing practices". There were not mny details. In an email, they have now told @TheWireScience the following :… (1/n)
"Problems were detected in some parts of the manufacturing process. SOME CHANGES WERE MADE after the emergency-use license was granted but were not submitted to the national drug regulator and WHO for evaluation and validation."
The WHO still didn't specify what were those changes. Whether those changes were related to increase the yield, or on the front of raw materials or due to some other reason--we don't know. A GMP expert said major changes, if done post approval, have to be informed.

The story of #Mild #Omicron Part 1
Long Thread -Story of 8 countries
Italy- Deaths due to Omicron have been higher than Delta by miles and almost reaching prevaccination levels .Vaccines were released around end December- Early January in most countries #OmicronIsNotMild ctd)
Ctd2)Denmark is second country- Again the Delta was decimated by the vaccines BUT with the Omicron the deaths have reached almost pre vaccine deaths #OmicronIsNotMild, #Omicron, #OmicronVariant , Also the Danes like others opened up after reaching good vaccination levels .
Ctd3) Country 3- Canada -Here too #Omicron crossed the deaths due to Delta by miles , reaching number of deaths before vaccination, in fact overshooting that number
#OmicronIsNotMild , needless to say the Canadians are fed up because it is #Mild in the media

💡We need to consider this vaccine—a whole virus traditional one that may add more protection versus variants (watch the🎥 why) & mRNA-vaccine-hesitant folks can be comfortable with. ➡️The FDA should honestly authorize #COVAXIN—EUA app submitted & waiting.
2) Notably, unlike a single target spike protein vaccine line mRNA ones or the adenovirus (J&J and AstraZeneca) ones, an inactivated whole virus traditional vaccine has multiple protein targets for which the body can “learn” to build recognition and immunity if spike is mutated.
3) P.s. I own **zero** stocks in COVAXIN makers. I’ve never traded their stock.

More than 40 lakh teenagers in the 15-18 age group received their first dose of #Covid19 vaccines on Monday. Some concerns were raised about ‘expired’ #Covaxin being administered to this younger group, leading to the Health Ministry issuing a clarification.
The Ministry described these claims as “false and misleading” and said these were based on “incomplete information”. It pointed out that the shelf life of #Covaxin, the only vaccine being given to the people below 18 years of age, had been extended:…
The Health Ministry said the shelf life of #vaccines is extended by the national regulator, Central Drugs Standard Control Organisation, or CDSCO, based on a comprehensive analysis and examination of stability study data furnished by the vaccine manufacturers.

The SmPC (Summary of Product Characteristics) for #Covaxin (see the link to Bharat Biotech's website here:…
has not been updated since the #EUA was granted for use in the 12-18 year age group. It still says (page 1):
"COVAXIN® is indicated for active immunization against SARS-CoV-2 Virus infection for age ≥18years."

The SmPC is a legal document that is part of the approval process. On the question of expiry date, it says:(page 10),
"6.3 Shelf life
The expiry date of COVAXIN® is indicated on the label and carton of the vaccine. Do not use the
vaccine after the expiration date shown on the label and carton of the vaccine."

💡[Whisper]… there is actually a proven vaccine for kids age 2-4 that is *CURRENTLY UNDER REVIEW* at the @US_FDA with an EUA app submitted on November 5th—but FDA has not moved yet on approval meeting. ➡️Why is the media not talking about this? #COVAXIN…
2) COVAXIN™ (BBV152) is a whole-virion, inactivated vaccine, manufactured using a Vero Cell manufacturing platform, as has been used in the production of the inactivated polio vaccine for the past 35 years, as well as of other traditional childhood vaccines.
3) The submission is based on results of a Phase 2/3 pediatric clinical trial conducted by Bharat Biotech in India with 526 children 2-18 years of age, which bridged immunogenicity data to a large, Phase 3 safety and efficacy clinical trial in nearly 25,800 adults in India.

#Covaxin vaccine was also reviewed by WHO’s Strategic Advisory Group of Experts on Immunization (SAGE), and recommended use of this vaccine in two doses, with a dose interval of four weeks, in all age groups 18 and above. #COVID19

Will the newly identified sub-lineages of #Delta may initiate a new wave of #Covid19 in India? What impact the increasing prevalence of the Delta-D clade would have on global #COVID burden?

My write-up deliberating on these issues in @TheWireScience 👇…

Additional Solicitor General Anil Singh for Union govt.

Kapadia: Policy is given to me last night. It isn't useful. It looks like the Union's "Near the Home" policy.

Kapadia: When all states can smoothly conduct this drive why are we struggling in #Maharashtra ?

#ThirdWave of #Covid is yet to arrive yet they are not coming up with a proper policy.

Reads out from the state's policy - It says "May be implemented."

Just got to read through the pre-print of COVAXIN phase 3 trial. Yes, it's reassuring that the efficacy against symptomatic COVID-19 is 77.8% and over 65% Delta variant. But, as a reader, I always wish to review through the methodology before interpreting the results (1/n)
Authors have defined symptomatic COVID-19 case as presence of at least two of the selected symptoms. It was not clear from the article whether an individual with only one symptom and tested positive was included in the analysis. Also, no definition given for severe COVID-19 (2/n)
It was not clear why only one Nasopharyngeal swab was taken among symptomatic individuals. Will both of these affect study result? It may affect. The study reports higher CT value in vaccine group. In that case, there may be lesser chance of detecting the virus among (3/n)

Desde fevereiro, quando protocolei um requerimento de informações com @TiagoMitraud sobre a compra da #covaxin pelo @minsaude, estou de olho neste contrato.

Em fevereiro, o MS anunciou compra de 20 milhões de doses da #covaxin, do laboratório indiano Bharat Biotech, no valor de R$1,6 bilhão. Entretanto, alguns fatos relacionados ao contrato chamaram a minha atenção e do deputado @TiagoMitraud .
