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.”


South Korea calls for resuming dialogue with North

South Korea calls for resuming dialogue with North

  • President Lee Jae Myung has sought to mend ties with the nuclear-armed North since taking office in June
  • North Korean leader Kim Jong Un last week dashed hopes of a diplomatic thaw with Seoul

SEOUL: South Korean President Lee Jae Myung called on Sunday for dialogue with North Korea to resume, after Pyongyang last week shunned the prospect of diplomacy with its neighbor.
Since taking office in June, a dovish Lee has sought to mend ties with the nuclear-armed North, which reaffirmed its anti-Seoul approach during a party meeting last week.
“As my administration has repeatedly made clear, we respect the North’s system and will neither engage in any type of hostile acts, nor pursue any form of unification by absorption,” Lee said in a speech marking the anniversary of a historical campaign against Japan’s colonial rule.
“We will also continue our efforts to resume dialogue with the North,” he said.
North Korean leader Kim Jong Un last week dashed hopes of a diplomatic thaw with Seoul, describing its overtures as “clumsy, deceptive farce and a poor work.”
Speaking at the party congress in Pyongyang, Kim said North Korea has “absolutely no business dealing with South Korea, its most hostile entity, and will permanently exclude South Korea from the category of compatriots.”
But he also said the North could “get along well” with the United States if Washington acknowledges its nuclear status.
Speculation has mounted over whether US President Donald Trump will seek a meeting with Kim during planned travels to China.
Last year, Trump said he was “100 percent” open to a meeting.
Previous Trump-Kim summits during the US president’s first term fell apart after the pair failed to agree over sanctions relief — and what nuclear concessions North Korea might make in return.
