World's First Covid Vaccine You Inhale Is Approved in China (bloomberg.com) 196

China became the first country to approve a needle-free, inhaled version of a Covid-19 vaccine made by Tianjin-based CanSino Biologics, pushing the company's shares up as much as 14.5% Monday morning in Hong Kong. From a report: China's National Medical Products Administration approved CanSino's Ad5-nCoV for emergency use as a booster vaccine, the company said in a statement to the Hong Kong Stock Exchange on Sunday. The vaccine is a new version of CanSino's one-shot Covid drug, the first in the world to undergo human testing in March 2020 and which has been used in China, Mexico, Pakistan, Malaysia and Hungary after being rolled out in February 2021. The inhaled version can stimulate cellular immunity and induce mucosal immunity to boost protection without intramuscular injection, CanSino said. Companies are looking into developing inhaled versions of vaccines to stimulate antibodies in nasal and airway tissues to defend against coronavirus. They are needle-free and can be self-administered, broadening their appeal to vaccine-hesitant people and potentially easing pressure on health-care resources.

    If the Chinese vaccines actually worked why is China still pursing their zero-covid lockdown strategy? Wouldn't forced vaccination be more effective?

    • The hit to their economy from lockdowns is worse than the purchase price of buying one of the Western vaccines from Moderna or Pfizer yet they insist on making their own.
    • China tried to do this and there was a public backlash that lead to a reversal.

      A vaccine mandate is much less intrusive than the current Chinese policy so I'm not sure why there was such fierce resistance.

    • It was just an excuse to prevent the Shanghai Faction of the CCP from wresting power from Xi's faction. Looks like it worked as pre-lockdown it was assumed they would take power.

    • Wouldn't forced vaccination be more effective?

      They did it like a lot of other countries: no access to some public places if you didn't get the vaccine. Also they never said it was so good(meaning 100% protection for 0 covid). In fact they said later that (at least) one of their vaccine was not effective... Most asian countries have covid policies which sound crazy to the rest of the world. For example, beloved Japan still forbids individual tourists and only allow guided tours.

    • This vaccine is new, the lockdown/zero covid policy obviously predates it.
      The previous vaccine, Sinovacc, is not very effective. Only roughly 70% - 75% after 2 shots.

      No idea how easy it is to vaccinate 1.5 billion people anyway.

      Vaccines don't stop you getting COVID. Look at the UK, high percentage of people double, triple or even quadruple vaccinated. Still millions got it this year and in excess of 2 million of them are suffering from Long COVID.

      Vaccines help slow the spread and reduce the severity of the symptoms, but a responsible government wouldn't take that as a sign that they can let COVID rip through the population.

    Since the ideal immunity to COVID starts with muccosal immunity, in the nasal cavity and in the lungs, that should be the best approach. And it was one of the first ways to be investigated. But apparently it's a difficult approach to make work. I wonder if this one will be both safe and effective.

      Presumably, the recipient wlil be protected earlier than the 7-14 days that the injections require. But I'd be surprised if it was more effective.

      What I don't get is why we're only on 2nd generation vaccines. The first gen are almost 2 years old at this point. AZ and J&J have known flaws. Some of the mutations of SARS-COV-2 are consistent across all strains. Mutations generally don't avoid a vaccine -- they change the shape of the virus and the proteins which means the antibodies for the old spikes

      • by HiThere ( 15173 )

        It should be more effective, since the first cells that get infected are along the airway. But this assumes that the vaccines produce equally strong immunitites. So it's not clear.

        If it works well, it could prevent "silent spreading" because the airway passages would be immune, so it couldn't grow there and spread from there before getting into the rest of the body.

    Can they spray it in caves and inoculate the bats ?
    • Good idea, bats have a lot more than coronavirus to offer, we should send more people in their caves to get our new gift.

      I've got nothing against conspiracy theories in general because if they didn't exist the PFY would probably have to join a book club or a sewing circle. But even the PFY will admit there's a limit, and at lunch today we think we found it ...

  • How long before Trump, Taylor-Greene & Alex Jones are saying that Chy-NAH will be infecting all true American patriots with this & to avoid Chinese businesses and...wait...for...it... to protect yourself by wearing Freedom Masks!

  • I trust nothing that China does with vaccines or public health. A country willing to starve or lock down millions of its own citizens over policy is not one I'd take any advice or technology from; the costs are too high.
