Sure. But it's not a peer-reviewed Lancet paper. It's just one (well-qualified) person's opinion who disagrees with the current prevailing view held by other well-qualified people.
Current prevailing expert opinion is that vaccination reduces the chance of being infected by about 30-40% with Omicron, based on observational and case control studies.
Some studies see no signal of reduced transmission. Other areas see massive effects. It's all confounded because the vaccinated do not behave exactly like the unvaccinated.
