Nasal vaccines the future in fight against COVID-19: UK scientist

  • Peter Openshaw, UK government advisor, suggests sprays could replace injections

LONDON: A leading UK scientist has suggested that COVID-19 could be effectively controlled through nasal spray vaccines, rather than injections, in the future. 

Prof. Peter Openshaw, a professor of experimental medicine at Imperial College London, described nasal immunizations as a “rational” development in the fight against the virus.

COVID-19 has been the subject of massive amounts of research into developing effective vaccines against the disease in record time, but all successful cases so far have involved injections.

There have also been fears that several of these early vaccines might become less efficient in the near future, with the emergence of a series of new variants of the virus, notably in the UK, Brazil and South Africa.

It is thought that nasal spray vaccines, as well as being easier to administer, would prevent the virus gaining a foothold in the body at an earlier stage.

“We really need to develop vaccines which are based on say nasal sprays and induce what we call a mucosal immune response,” Openshaw, a scientific advisor to the UK government on its New and Emerging Respiratory Virus Threats Advisory Group, told the BBC. 

“The initial vaccines given to us as an injection induce a very good response in your bloodstream and also protect the lungs pretty well … in terms of antibodies. But getting a nasal response would be a really good way to develop vaccines in the future.”

Trump fires homeland security chief Kristi Noem

  • Trump, in a post on Truth Social, said Markwayne Mullen, a Republican senator from Oklahoma, would take over from Noem
  • Trump: Noem ‘has served us well, and has had numerous and spectacular results (especially on the Border!)’
WASHINGTON: US President Donald Trump on Thursday fired Kristi Noem as head of the Department of Homeland Security, the agency responsible for carrying out his sweeping immigration crackdown.
According to multiple media reports, Trump was upset with Noem’s testimony at a Senate hearing this week where she said the president had approved a $220 million DHS advertising campaign in which she featured prominently.
Trump, in a post on Truth Social, said Markwayne Mullen, a Republican senator from Oklahoma, would take over from Noem at the powerful department on March 31.
The president said Noem, 54, would become his special envoy for a new security initiative in the Western Hemisphere he called “The Shield of the Americas.”
Noem “has served us well, and has had numerous and spectacular results (especially on the Border!),” Trump said.
Trump described Mullin as a “MAGA Warrior” and said he will be a “spectacular Secretary of Homeland Security.”
Mullin’s nomination will be subject to confirmation by the Senate, where Republicans hold a majority.
“Markwayne will work tirelessly to Keep our Border Secure, Stop Migrant Crime, Murderers, and other Criminals from illegally entering our Country, End the Scourge of Illegal Drugs and, MAKE AMERICA SAFE AGAIN,” Trump said.

Deportation policy

The Republican president campaigned for the White House on a pledge to remove millions of undocumented migrants from the United States and DHS is the chief enforcer of his deportation policy.
Noem came in for bipartisan criticism at Tuesday’s Senate hearing over the Trump administration’s immigration crackdown.
“Under your leadership, the Homeland Security Department has been devoid of any moral compass or respect for the rule of law,” Senator Dick Durbin, a Democrat from Illinois, told Noem.
Durbin and other Democrats repeatedly asked Noem to apologize for the deaths of two Americans shot dead by federal agents in Minnesota during protests against the immigration crackdown and for calling them “domestic terrorists.”
Senator Thom Tillis, a Republican from North Carolina, had harsh words for Noem’s tenure at DHS and called for her resignation.
“What we’ve seen is a disaster under your leadership,” Tillis said. “What we’ve seen is innocent people getting detained that turn out are American citizens.”
Senator John Kennedy, a Republican from Louisiana, questioned Noem about the $220 million spent by DHS on television advertisements urging undocumented migrants to self-deport.
Noem said the advertisement campaign had been “effective.”
“They were effective in your name recognition,” Kennedy shot back.
Noem’s firing comes amid a partial shutdown at DHS.
Democrats oppose any new funding for DHS until major changes are implemented to how the Immigration and Customs Enforcement (ICE) agency conducts its operations.
They have demanded curtailed patrols, a ban on ICE agents wearing face masks and a requirement that they obtain a judicial warrant before entering private property.
