Covid-19 news: Moderna’s omicron booster has promising immune response - New Scientist

A regular round-up of the latest coronavirus news, plus insight, features and interviews from New Scientist about the covid-19 pandemic A Moderna covid-19 vaccine is prepared Dinendra Haria/SOPA/Shutterstock Latest coronavirus news as of 1pm 9 June Moderna’s omicron-tailored booster candidate produces eight times as many virus-neutralising antibodies against the variant as its original booster vaccine An updated version of Moderna’s covid-19 vaccine that targets the BA.1 sublineage of omicron leads to an eight-fold increase in antibody levels against the variant of concern, according to a small, preliminary study. Moderna’s new booster is the first covid-19 vaccine to combine the jab that targeted the original strain of the coronavirus – which emerged in Wuhan, China, at the end of 2019 – with a vaccine that specifically targets the omicron variant. In the clinical trial, the updated vaccine was given to 437 people who had already received two full-dose Moderna vaccines and its booster. One month after receiving the updated booster, the participants’ neutralising antibody levels against omicron had risen by about eight times. “The data we show today are really important because we get a really strong antibody response against Omicron,” Moderna’s chief medical officer Paul Burton told The Guardian on 8 June. “For the first time, we could really be looking at the potential for just once-yearly boosting, because we can get people to such a high level that they will take longer to decay.” Whether these raised antibody levels translate into a reduced risk of hospitalisation or death with covid-19 is unknown. “These antibody measurements provide an indication that is likely to translate into clinical effects, but an element of uncertainty in extrapolating the results to clinical effectiveness must, inevitably, remain,” Stephen Evans at the London School of Hygiene & Tropical Medicine said in a statement to the Science Media Centre. Other coronavirus news India has reported its highest number of daily covid-19 cases since March. The country’s health ministry reported today that 7240 new coronavirus infections had occurred in the last 24 hours. Shanghai in China will lock down 2.7 million people while it conducts mass coronavirus testing. This comes just one week after the city eased restrictions that had confined about 25 million people to their homes since March. As of 11 June, people living in the south-western district of Minhang will be placed under “closed management” until they have all been tested.

People walking along Westminster Bridge in London in May Amer Ghazzal/Shutterstock 1 June An estimated 2 million people in the UK have lingering covid-19 symptoms more than four weeks after their initial coronavirus infection Based on the latest Office for National Statistics (ONS) survey of people living in private households in the UK, an estimated 3.1 per cent of the population were experiencing long covid symptoms as of 1 May. This is 200,000 more people than the ONS’s previous estimated prevalence of 1.8 million, as of 3 April. Of the estimated 2 million people with long covid, 1.4 million are thought to have been infected, or suspect they were infected, at least 12 weeks prior to their ongoing symptoms. Meanwhile 826,000 are estimated to have been infected with covid-19, or had a suspected infection, at least one year earlier. About 376,000 would have first been infected at least two years ago. Of those surveyed, 55 per cent with long covid had fatigue, the most commonly reported symptom. This was followed by 32 per cent of people experiencing shortness of breath, 23 per cent having a cough and 23 per cent experiencing muscle aches. Other coronavirus news Three doses of a coronavirus vaccine, regardless of what type, are the most effective defence against covid-19, a study has found. Researchers at the Chinese University of Hong Kong (CUHK) analysed 53 vaccine studies conducted throughout the pandemic. The studies included over 100 million participants who together received seven different types of covid-19 vaccines in 24 dosing combinations. Results suggest three doses of any mRNA vaccine, such as those manufactured by Pfizer/BioNTech and Moderna, is 96 per cent effective against asymptomatic and symptomatic covid-19 infections, accounting for the different variants. An mRNA booster after two doses of an adenovirus vector vaccine, such as those manufactured by AstraZeneca/The University of Oxford and Johnson & Johnson, is 88 per cent effective. Despite higher efficacy with a three-dose mRNA vaccine regimen, three doses of any covid-19 vaccine is still very effective, according to the researchers. A third of people in the UK think the government is exaggerating the number of covid-19 deaths, a study has found. Researchers at King’s College London surveyed 12,000 people about their views on covid-19 across six countries: the UK, Ireland, Italy, Germany, Norway and Poland. A third (33 per cent) of people in the UK believe the government is exaggerating the number of covid-19 deaths, a figure that is even higher in Poland, at 43 per cent. Norway has the lowest proportion of people who do not trust the government’s mortality figures, at 24 per cent. The researchers also found that 15 per cent of people in the UK do not believe that nearly all scientists think the covid-19 vaccines are safe. “Across both the UK and other European countries included in this study, there is a stubborn minority who still question not only the scientific consensus on vaccine safety but also government reporting of Covid deaths,” Bobby Duffy at King’s College London in the UK said in a statement.
