Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

Sir: Mrs J Mathews suggests that the rise in asthma may be connected with multi-vaccination at an early age (letter, 14 January).

Two years ago I went to Cuba on holiday. While I was on a group visit to a collective farm the resident nurse was asked about the main medical problems encountered locally. She said that one of their main concerns was the steady increase in childhood asthma. On further questioning it was apparent that the asthma trends in Cuba over the last few decades have been broadly similar to those in the UK.

One would think that the environments were quite different; especially that Cuba has very little road traffic pollution, because it has very little road traffic. Climate and diet are different. One thing that Cuba does have in common with the UK is a comprehensive public health service, including mass childhood vaccination.

I would be tempted to jump to the conclusion that Mrs Mathews has hit the nail on the head, but Tony Bosworth of Friends of the Earth points out on the same page that some kinds of air pollution are felt a long way from their source. So asthma in Cuba and the UK might both be caused by global pollution of some kind. However, the coincidence of the vaccination programmes deserves close study.
